Filed: 1989-11-30
Abstract: PURPOSE:To always exhibit a satisfactory silencing characteristic by providing a gain control means and controlling gain for input side and output side gain controllers with a condition to keep the whole gain constant corresponding to the input end signal level of an input side gain controller sensor. CONSTITUTION:A gain controller 29 is equipped with a peak value detecting circuit 30 and an average value detecting circuit 31 for an input signal. The outputs of the both circuits are led into a gain deciding circuit 32. Based on the both outputs, the gain deciding circuit 32 calculates the gain so that an A/D converter 24 can convert an input level to a level to be processed by using a full word length. When the input signal level of an input side gain controller 22 is low, the gain of the controller 22 is increased and the gain of an output side gain controller 27 is decreased only for the increased part. When the input signal level is high, the operation is executed reversely to the above mentioned operation. Therefore, the level of the signal is adjusted so that the bit resolution of the A/D converter 24 can be always maximum, and the satisfactory silencing characteristic can be always exhibited effectively.
