WebThis block diagram of FM receiver is similar to the block diagram of AM receiver. The two blocks Amplitude limiter and De-emphasis network are included before and after FM demodulator. The operation of the remaining blocks is the same as that of AM receiver. We know that in FM modulation, the amplitude of FM wave remains constant. WebMar 23, 2024 · Frequency Modulation: Frequency Modulation is a modulation in which the frequency of the carrier wave changes according to the instantaneous amplitude of the modulating signal keeping phase and amplitude constant. The frequency of the carrier wave is modified in order to send the data or information.
