Title: Agc circuit
Inventor: HAMASUNA HIDEKUNI
IPC: H04N5/52
Filed: 1989-08-19
Abstract: PURPOSE:To prevent the operation of automatic polarity from being affected even when temperature changes by connecting a resistor having a temperature characteristic to the base circuit of a transistor(TR) of a video amplifier stage in an AGC loop. CONSTITUTION:A thermister TH is connected in series with a resistor R3 connected between ground and the base of a TR Q1 of a video amplifier stage in an AGC loop. The thermister TH has a negative temperature coefficient to cancel a change in an AGC voltage due to temperature, thereby preventing the AGC voltage from being affected by temperature. Thus, even when the AGC voltage is supplied to an antenna as an automatic polarity voltage, the operation of automatic polarity is not affected by temperature and a large effect on the reception even when in a strong electric field is prevented.
