“WHAT DO YOU WANT to be when you grow up?” More than one professional chef got his start with an Easy Bake Oven. Here are some ideas for children 8 and up that just may inspire your child to be a scientist, engineer or designer. Science. Thames & Kosmos produces serious science kits that teach concepts and skills through handson modeling of real-world devices and processes. The manuals make for a rich learning experience. Students can learn how to build fuel cells, discover the science behind climate change, and learn the chem- Kids coughing? A new study from Penn State College of Medicine shows a simple, over-the-counter remedy that has been used for generations really works. Vapor rub (menthol, camphor and eucalyptus oils) applied to children’s chests at bedtime reduced kids’ cough frequency, cough severity and congestion and helped them sleep better. Engineering. If your children can’t get enough of amusement park rides, the Science of Disney Imagineering DVD series will open their eyes to the power of the attractions. The educational series uses physical and visual examples that demonstrate how science (magnetism, friction, trajectory) puts the magic in the rides.

Integrated Circuit FM Receiver using Bipolar Linear ... - Working Group

Even if FM radio broadcasting is a fundamental means of communication, it can’t escape one of the big trends in electronics today: miniaturization. As mobile communication devices are gaining more and more functionalities, people still want to have the option of listening to FM radio on their smart phones or MP3 players. This can only be achieved through the miniaturization of the FM reception process by implementing all its functions into a microchip. This miniaturization process is widely used in the industry, but has not been explored in depth by undergraduate students. In order to appreciate the complexity of such a task, we decided to design an FM receiver in a microchip. To make the project more interesting, we chose to create a user interface facilitating its use.

Part- FM Superhet

The design of FM receivers for broadcast reception are generally low-cost single conversion designs. The system comprises the front end, the IF amplifier plus limiter, and the detection stage. The latter two are nowadays almost always part of an integrated circuit to reduce costs. Until about the early 1990s the FM front end has always been constructed using two transistors. In a bid to further reduce costs and make the design simpler to manufacture, various manufacturers had begun to offer integrated circuits that provide a complete FM front end with just the addition of external tuned circuits. From about the mid 1990s and to the present day, semiconductor vendors have offered even greater integration, with a complete FM-AM receiver in a single chip, including a 1-watt audio amplifier, requiring minimal external circuitry. However the complete end-to-end analog design is meeting its end, as everything is moving to digital broadcasting. Nonetheless the techniques presented here remain valid, regardless of whether the radio carries analog audio or digital bitstreams. The following describes in detail, designs used for virtually all mass-produced radio sets,...

Design of Integrated, Low Power, Radio Receivers in ... - Virginia Tech

Despite increasing levels of integration in modern electronic products, radio receiver designs continue to rely on discrete LC, ceramic, and electro-acoustic devices for the realization of RF and IF bandpass filtering. Although considerable research has been directed at developing suitable switched-capacitor and Gm-C based replacements for these filters, the resulting designs have yet to see substantial commercial application. A critical problem faced by existing active filter implementations is found to be the power consumption required to simultaneously achieve narrow fractional bandwidths and acceptable dynamic range. This power consumption, which can reach several hundred milliwatts, is incompatible with portable wireless product design. Additional problems include the complexity of tuning control circuits required to achieve small fractional bandwidths, and difficulties in extending filter designs to higher frequencies. These problems are examined in depth, and performace bounds and new implementation techniques are considered. A detailed study of active filters reveals that their dynamic range limitations are fundamentally the result of regenerative gain associated with the realization of high-Q poles. Thus, some form of energy storage and exchange mechanism is shown to be required to decrease the regeneration needed. This leads to an investigation of on-chip LC filtering. It ...

Design of All Digital FM Receiver Circuit - OpenCores

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.

NTE788 Integrated Circuit IF System for FM Receiver

The NTE788 is a monolithic integrated circuit in a 16–Lead DIP type package that provides all the functions of a comprehensive FM–IF system. This device features a three–stage FM–IF amplifier/limiter configuration with level detectors for each stage, a doubly–balanced quadrature FM detector, and an audio amplifier that features the optional use of a muting (squelch) circuit. The advanced circuit design of the IF system includes desirable deluxe features such as delayed AGC for the RF tuner, an AFC drive circuit, and an output signal to drive a tuning meter and/or provide stereo switching logic. In addition, internal power supply regulators maintain a nearly constant current drain over the voltage supply range of +8.5V to +16V. Features: D Exceptional limiting sensitivity: 12µV typ. at –3dB point D Low distortion: 0.1% typ. (with double–tuned coil) D Single–coil tuning capability D Improved S + N/N Radio D Externally programmable recovered audio level D Provides specific signal for control of interchannel muting (squelch) D On channel step for search control D Provides programmable AGC voltage for RF amplifier D Internal supply–voltage regulators D Externally programmable “ON” channel step width, and deviation at which muting occurs...
