To recover the data from a modulator carrier wave – a demodulator signal circuit comes in use. There are different types of demodulators too. The demodulator output signal may describe as a sound, binary data, or pictures. Need for Demodulation northern nj outdoor diningThere 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… northern nl train care address
