Title: Agc circuit for fax receiver
Inventor: YUDA HIROTOMO
IPC: H04N1/40
Filed: 1989-02-28
Abstract: PURPOSE:To allow the circuit to cope with fluctuation of a level of an AGC voltage caused by an invaded high level noise by integrating a demodulated FAX signal with a prescribed charge discharge time constant and controlling the discharge time constant of the AC voltage when an integrated voltage is decreased lower than a set threshold voltage. CONSTITUTION:When a noise output S11 due to a high level noise P1 appears in an output signal (b) of an amplifier 11, an AGC control circuit 6 charges the noise voltage quickly and the AGC voltage (f) rises to a voltage V3 within a time corresponding to the charging time constant. Thus, the gain of the variable gain amplifier 1 is decreased. Then no demodulation signal (c) exists at the output of a demodulation circuit 2 and the integration voltage (d) of the integration circuit 3 is discharged gradually. When the voltage is lower than a threshold voltage V1 of a level comparator circuit 4, the AGC constant control circuit 5 receives an H level input from the level control circuit 4 to control the discharge time constant of the AGC control circuit 6 thereby discharging the AGC voltage (f) momentarily and lowering the voltage.
