COMMUNICATIONS IN PROCESS CONTROL (PART 1)

The last decade has seen many new measurement and control techniques developed.This has been principally due to the development of low cost electronic circuits and, more recently, the microprocessor.As a result of this rapid development the instrument Verde Frame and process control engineer is faced with the arduous task of interfacing new and old

We propose a robust microphone array for speech enhancement and noise suppression.To overcome target signal cancellation HRC BOARD problem of conventional beamformes caused by array imperfections or reverberation effects, the proposed method adopts arbitrary transfer function relating each microphone and target speech signal as array channel model.
