Background The web browser uses Oracle’s Java software to launch the Gradkell Systems Universal WebSigner JAVA applet, which enables your Common Access Card (CAC) to access DTS. Due to increased security within JAVA, outdated versions of JAVA will be unable to launch the Universal WebSigner applet (as well as many other applets for other websites) without lowering JAVA’s security. Check with your organization’s IT office for specific guidance. The Travel Assistance Center offers two potential workarounds, if applicable. Workarounds First, check the version installed on your workstation. Go to Control Panel, Java, and click the “About” button. The version will be displayed. Workstations using older versions of Java 7 (usually update 25) have two options. • Option 1: Upgrade to the latest version of JAVA from www.java.com. o Workstations using the latest version of JAVA will continually get error messages about whether to let the DBsign Universal WebSigner applet run but will be allowed to login to DTS. o Pay close attention to the warnings that appear and answer accordingly so the DBsign Universal WebSigner is not blocked and allowed to run. Depending on your operating system and version of Internet Explorer, the error messages may vary (see figure below.)

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,...
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.
FM RECEIVER CIRCUIT FOR BATTERY SUPPLY DESCRIPTION The SC1088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a minimum of perpheral components (of small dimensions and low costs) is important. The circuit contains a frequency-locked-loop(FLL) system with an intermediate frequency(IF) of about 70kHz. Selectivity is achieved by active RC-filters. De-tuning related to the IF and too weak input signal is suppressed by the mute circuit. FEATURES * Equipped with all stages of a mono receiver from antenna to audio output. * Mute Circuit * Search tuning with a single varicap diode * Mechanical tuning with integrating AFC * AM application supported * Power supply polarity protection * Power supply voltage down to 1.8V SOP-16 APPLICATION 1. Mechanical tuning: This is possible with or without integrated AFC circuit 2. Electrical tuning: This is realized by one directional(band-up) search tuning facility, including RESET to the lower-band limit.
