Abstract

PURPOSE:To accommodate the change in gain at each cycle of repeated transmitting pulse by means of an open loop control circuit so arranged that the prescribed control error is attained within the time range corresponding to the pulse width of a pilot pulse signal. CONSTITUTION:The picture transmitting IF signal of the gain control circuit 19 is detected in the absolute value of the amplitude with a wave detector 16 of an amplitude detection circuit 200, whose output is converted into the digital value with an AD converter 17. Thus, the absolute value of the amplitude of the pilot pulse signal is outputted in the digital value. The control circuit 18 computes the gain control value from the difference between the digital amplitude output and the prescribed reference amplitude value and outputs a digit 1 gain control signal timed for the sample gate signal. The gain control circuit 19 executes a gain control by the gain control output of the control circuit 18.
