Abstract

PURPOSE:To make it possible to fulfill pulse noise detection by detecting a pulse noise by holding the continuous noise in the output of a differential amplifier at a constant level. CONSTITUTION:A high-pass filter extracts a high-frequency component in an input signal and its output signal is differentially amplified 10; and the feedback circuit composed of diodes 28, 29, 30, and 31, and transistors Trs 26 and 27 holds at a constant level a continuous noise contained in collector output of components Tr11 and Tr12 of amplifier 10. Next, the pulse noise is detected by voltage-dividing resistors 36 and 37, and detection Tr38 and then outputted 41. Consequently, the pulse noise can be detected accurately by keeping the continuous noise level constant.
