Figure 1.1 shows the block diagram of the invention. The non-limited FM signal F1 is mixed to form the less modulated FM signal F20. It passes at least through a filter with narrow bandwidth and goes to the limiter as F21. The limited signal F22 is demodulated in an FM demodulator of ...

The receiver structure in this block diagram represents the FMReceiverSimulinkExample.slx model used in this example. The processing has three main parts: signal source, FM broadcast demodulation, and audio output. Signal Source This example can use three signal sources: ''Captured Signal'': Over...
a demodulation means 22 for outputting the additional information data, a sound recording means 40 for recording the main sound signals, an input means 30 for setting music data relating to the desired music, a memory means 28 for storing the music data set in the input means 30, a display...
The MLL ,as shown in figure 3.7,can be used for demodulation of FM ,The input frequency to the VC transfer function is found to be of the first order . The MLL can be used for precision frequency synthesis. The block diagram is shown in Figure 3.9.The frequency depends only on a sing...
