Circuit arrangement for a television receiver with a controllable intermediate-frequency video signal amplifier

摘要

The invention concerns a circuit arrangement for a television receiver for positively modulated video signals with a controllable intermediate-frequency amplifier (2). The output (3) of the intermediate-frequency amplifier (2) is coupled via a limiter (5), which essentially limits the picture content of the video signal, to a mean-value detector (7). An integrator (11), which is connected thereafter in series, generates the control signal for the intermediate-frequency amplifier (2). IMAGE
