Title: Signal compensating gate circuit for pulse noise rejection
Inventor: AMASAWA KIYOSHI
IPC: H03G3/34
Filed: 1985-02-12
Abstract: PURPOSE:To apply effective signal compensation to an input signal even with a long switching time by constituting the titled circuit that a signal having the same frequency and level as those of an input signal is outputted at noise detection in an audio equipment such as a car radio set so as to compensate the waveform of the input signal. CONSTITUTION:The signal with the same level as an audio signal is generated always from a level control means 24. The signal outputted from the means 24 is fed to a buffer amplifier 8 to apply waveform compensation to the audio signal. The value of a capacitor C1 to apply the audio signal as the input signal to a signal generating means 23 and a level control means 24 is selected to cut off a low frequency and to pass through only a high frequency requiring signal compensation. A switch 14 connected to an attenuator 18 is turned off during the time with a delayed response and the switch 14 is turned on at the state when the signal compensation is tracked so as to apply signal compensation completely.
