摘要:
A tuner has an intermediate-frequency amplifier and an automatic gain control which are connected to form a loop. A detector is connected to an input side of the intermediate-frequency amplifier so as to be applied with a signal to be applied to the intermediate-frequency amplifier. A logarithmic amplifier is provided for producing an output for logarithmic display on a signal meter.
