In Synchronous Detection Of Am Signal? |
|
Answer» In synchronous detection of AM signal, the CARRIER signal is locally generated and then passed through a LOW pass filter. At the output of the low pass filter, the original modulating signal is recovered. The synchronous detection requires the generation of carrier at the receiver ALSO. So ADDITIONAL CIRCUITRY is required at the receiver. In synchronous detection of AM signal, the carrier signal is locally generated and then passed through a low pass filter.
