WebThis video describes how a Pulse Counting FM Discriminator works - it is a unique FM demodulator that doesn't require and tuned circuits like the FM Ratio Detector or Foster Seeley discriminator. WebDec 24, 2024 · In demodulation part program make some fundamental calculation for FM detection, then to obtain message signal it uses filter. Last part program plots the graph of recovered signal with message signal to compare them. I summarized all code because ı do not know whre is the problem.
WebThe demodulation is almost complete with the filter circuit but to use the demodulated signal for some useful purpose one more step has to be performed. The output of the … WebA typical spectrum of the FM radio signal is shown in Figure 3 below. Note that this is the spectrum of m(t), the multiplex signals contained within the message signal m(t), instead of u(t). Use this as a reference for comparison when looking at the spectrum of the demodulated received FM signal. Figure 3 - A typical spectrum of a FM radio signal 1, note …
