Abstract :
This paper describes implementation of frequency domain digital filter for speech enhancement. The signal enhancement system in view of speech quality in the frequency domain in particular is discussed. In telephone communication, the spectrum extrapolation which employs aliasing processing is widely known. Implementation of the speech enhancement system and its performance are discussed and a new implementation using adaptive methods is proposed
