PPT-Chapter 7. Analog Communication System

Husheng Li The University of Tennessee Superheterodyne Receiver Four tasks of the receiver Demodulation Carrier frequency tuning Filtering Amplification of signal In theory all of the foregoing requirements could be met with a highgain tunable . For the test and measurement industry however the front end design is not as simple because this application area often requires the input signal to be DCcoupled as well as provide the capability for ACcoupling The design of an active front end that 1 Oscillation results from an unstable state ie the feed back system cant find a stable state because its transfer function cant be satisfied Equation 1 becomes unstable when 1A 0 because A0 is an undefined state Thus the key to designing an oscil Husheng Li.
