Abstract
PURPOSE:To prevent knocking signal to be attenuated by ripples by providing an autogain control. CONSTITUTION:An autogain control AGC consists of two systems. One of two systems is a knocking signal amplifier circuit, and the other is a BLG output circuit. If BLG which is an output of an integrated circuit 1, including ripples, is directly applied to the input of the AGC circuit, knocking signals are attenuated by ripples. An integrated circuit 3 further averages BLG so as to remove ripples for preventing the attenuation of the knocking signals, and generates input signals to the AGC circuit. Thereby, the attenuation of knocking signals due to ripples is prevented.
