WebJul 30, 2024 · Demodulator The received modulated signal is now demodulated with the same process used at the transmitter side. The frequency discrimination is generally used for FM detection. Audio Amplifier This is the power amplifier stage which is used to amplify the detected audio signal. The processed signal is given strength to be effective. There are several ways of demodulation depending on how parameters of the base-band signal such as amplitude, frequency or phase are transmitted in the carrier signal. For example, for a signal modulated with a linear modulation like AM (amplitude modulation), we can use a synchronous detector. On the other hand, for a signal modulated with an angular modulation, we must use an FM (frequency modulation) demodulator or a PM (phase modulation) demodulator… east boothstown consultationWeb4.2 Designing and Simulating an FM Demodulator Following the block diagram of the PLL-based FM demodulator you have drawn on your preparation sheet, build a new model in Simulink.
