Title: Eliminating device for impulsive noise in fm receiver
Inventor: KAWAKAMI YASUO
IPC: H04B1/10
Filed: 1988-03-07
Abstract: PURPOSE:To prevent misdetecting noise except impulsive noise for the impulsive noise and to improve a detecting accuracy by setting impulsive noise detecting sensitivity according to the peak value of the high band component of a received detecting signal. CONSTITUTION:The high band component of the output signal of an FM detecting circuit 1 is extracted by an HPF 6, full-wave-rectified by a rectifying circuit 8, and supplied to a comparator 10 and a control signal generating circuit 16 in containing the noise except the impulsive noise. The control signal generating circuit 16 generates a voltage to follow the peak value of the output voltage of the rectifying circuit 8 in making it into a control signal, and an AGC error amplifier 13 fed back a direct current signal according to a level difference between the control signal and a second reference signal to a noise amplifier 7. Consequently, since a control signal level is raised and the gain of the noise amplifier 7 is lowered as the peak value of an input noise signal is made large, the detecting sensitivity of the impulsive noise is lowered. Since the detecting sensitivity is changed according to the control signal level, the impulsive noise can be surely detected.
