Communication Engineering - Pre-emphasis and De-emphasis

This video lecture is about the Pre-emphasis and De-emphasis. To increase the SNR at higher modulation frequencies, a high pass circuit called pre-emphasis, is used at the transmitter. Another circuit called de-emphasis, the inverse process of pre-emphasis is used at the receiver, which is a low pass circuit. The pre-emphasis and de-emphasis circuits are widely used in FM transmitter and receiver to effectively increase the output SNR.
Typical Pre-emphasis Circuit, Pre-emphasis Characteristics, De-emphasis Circuit, De-emphasis Characteristics have been drawn and explained.
