1. Introduction The design of the All Digital FM Receiver circuit in this project uses Phase Locked Loop (PLL) as the main core. The task of the PLL is to maintain coherence between the input (modulated) signal frequency, ωi and the respective output frequency, ωo via phase comparison. This self-correcting ability of the system also allows the PLL to track the frequency changes of the input signal once it is locked. Frequency modulated input signal is assumed as a series of numerical values (digital signal) via 8-bit of analog to digital conversion (ADC) circuit. The FM Receiver gets the 8 bit signal every clock cycle and outputs the demodulated signal. The All Digital FM Receiver circuit is designed using VHDL, then simulated and synthesized using ModelSim SE 6 simulator and Xilinx ISE 6.3i, respectively. FPGA implementation also provided, here we use Virtex2 device. The real measurement is done using ChipScope Pro 6.3i. 2. Architecture Description The system of All Digital FM Receiver consists of a digital PLL cascaded with digital low pass filter. The block diagram of system is shown in Fig. 1.
If you're a thrifty soul like I am (notice I didn't say cheap), you'll want to save some dough by doing your oil change yourself. It's really easy, doesn't take a lot of muscle or time, and you can spend what you save by doing it yourself on some toys for your bike. Having previously purchased the Honda Service Manual (I figured it oughta come in handy for more than just an oil change), I purchased my supplies to do my own oil change at 4000 miles. I bought the Honda oil filter wrench because you can put a 3/8" drive ratchet on it to loosen or tighten the filter. It's not cheap, but it's a good one-time investment for your bike. If you've ever changed the oil and filter in a 4-wheel vehicle, it's the same concept, everything's just in a different place. Following the Service Manual, here's what I did. All sections italicized are direct quotes from the Honda Service Manual. NOTE: Change the engine oil with the engine warm and the motorcycle on its side stand to assure complete and rapid draining. Start the engine and let it idle for a few minutes to warm the oil. Remove the oil dipstick. This provides an air gap for the oil to flow freely while draining. Locate the oil drain plug. It is on the left side, at the bottom of the engine. There is not enough space to use a ratchet, so I used a 17mm combination wrench. The open end included in your bike's toolkit will work fine. Loosen the drain plug, then place a drain pan under the drain plug. Remove the drain plug. Let the oil drain into the drain pan. Now the manual states: With the engine stop switch "OFF", push the starter button for a few seconds to drain any oil which may be left in the engine. NOTE: Do not operate the motor for more than a few seconds.
THE PERFECT OIL CHANGE The “Perfect Oil Change” is the easiest thing in the world to do. The problem is that oil changes are often seen as a chore, and the necessary time and attention are often skimped in the rush to get to something that seems more important. You may well be the first owner of the tractor to do this right. The first step is to get the motor good and hot. Run it for at least a half-hour, until the cylinder head is too hot to touch and the oil filter can is uncomfortably warm. This ensures that the oil is hot, which makes it flow easier, and it also makes sure that any crud in the oil is fully entrained and will come out with it. Park it, shut it off, and immediately remove the drain plug on the underside of the engine. Have a drain pan that will hold 6 quarts of oil under the drain. You’ll get a hot, oily hand, because the drain hole is big and most of the oil will come out in one big rush. Once that is draining, turn to the oil filter can, on the left side of the engine. Remove the cap by undoing the big hexagon bolt on the top. Don’t remove the filter yet. Next, locate the drain plug for the filter can – it’s on the bottom of the can, towards the front. It may have a hexagon head, or it may have a square head – either way, it’s usually all boogered up from people using pliers to remove it. Remove it, with a drain pan under the hole – this will allow the oil in the filter can to drain out. Now – go away and leave it alone. Find something else to do, but leave it to drain for at least an hour,...
Changing the sixth generation Corvette Oil Difficulty: 2 out of 5. Time required: Plan on about 1.5 hours taking your time. Tools required: Ramps, Floor jack, Jack stand(s), 13mm wrench or socket, Oil filter wrench, lifting puck, wheel stops, shop rag. Materials required: 1 compatible oil filter, 6 quarts of compatible oil. Capacities are 5.5 Quarts with a filter change for the non-Z51 and 6 quarts with a filter change on the cars with the RPO Z51. Recommended oil is Mobil 1 fully synthetic 5W-30 (GM spec 4718M). Recommended Oil filter is GM UPF44 (2005), UPF46 (2006) UPF48 (2007-2009) If you have access to a lift you can skip to step 6. If you are doing this at home without access to a lift continue to the photos below. Step 1. Get the car up in the air. I use a couple of 2x4’s and my rhino ramps. The 2x4’s will give enough clearance to get up on the Rhino ramps without deflecting the side air dams. Step 2. Get yourself a little more clearance on the driver’s side for easier access to the oil drain plug and filter. Once I have the car up on the ramps I take my floor jack and jacking puck and raise the drivers side further. Don’t forget to block the rear tires once you have the car up on the ramp. Step 3. Get yourself some extra room. Once the jack is in place and the car is up out of the way I will turn the ramp around so that you have easy access behind the tire. Step 4. Place a jack stand up front under the frame support and lower the car back down. Now that the car is lifted and safely supported you can begin the process of changing out the oil. Step 5. Place your oil pan under the drain plug. I like to use a piece of cardboard under the drain pan to collect any oil that may miss the pan during the process of removing the...
Motor Oil Place the bike on the center stand (not the kick stand) The Drain Plug and the Dipstick for the motor oil are located on the right side of the bike. Place a drain pan under the Drain Plug and remove the plug with a 17mm socket or wrench. Lancepowersports.com A small spring and Screen Type Oil Filter will also pop out. Place these two items off to the side and wash them clean by flushing them with new 10W-40 motor oil. (If you keep the dipstick out of the motor, it will drain the oil faster) Let the motor oil drain until only a few drops fall every few seconds. Put the cleaned Oil Filter and the spring back into the engine as shown to the left. If done incorrectly, the filter will not be efficient in collecting dirt and sludge from the engine. Screw back on the drain plug using a torque wrench. The recommended torque for this bolt is 15 lbs/ft. Lancepowersports.com Using a funnel, pour 0.75 quarts of 10W-40 Motor Oil into the engine. We recommend using non-synthetic oil for the first oil change to help the engine break in properly. After the first oil change, feel free to use synthetic oil. Check the oil with the dipstick. Place the dipstick in the motor but do not screw it in. Pull it out and make sure that the oil reading is within the hash-marks, then add or drain oil accordingly until it is. Screw in the dipstick and run the bike for a minute or two and check the level to make sure that you have the proper level. Lancepowersports.com
Softail Oil Change From time to time I see question on the forum regarding doing an oil change on a Harley and more specifically about doing a scavenging oil change on a Softail. Since there didn't seem to be a good thread on doing an oil change with pictures, I thought I would write something up. This oil change was done on a 2001 Fat Boy. So, some of the tools and procedure may be different for your specific application. Tools Motorcycle lift 1/4" Allen head socket or long Allen head tool (for engine oil and transmission oil drain plugs) 3/8" Allen head socket or Allen head tool (transmission oil fill plug) 3/8" drive ratchet wrench 6" long 3/8" drive extension 3/8" drive universal joint (may or may not need depending on bike location on lift) 1/4" drive ratchet wrench T27 Torx head socket or torx head tool (primary cover screws) T40 Torx head socket or torx head tool (primary oil drain plug) Oil filter wrench Oil catch tool for filter (optional) Oil drain pan (preferably 2) Flashlight 3/8" Fuel / Oil line removal tool (Scavenging oil change ONLY) Clear tygon tubing (Scavenging oil change ONLY)
