AUTOMATIC GAIN CONTROLLER |
摘要 |
A television receiver receives a scrambled television signal of the suppressed sync pulse type. The sync pulse is restored by a decoder which provides a sync restored video signal to video signal processing circuits of the receiver, and to automatic gain control circuits of the receiver via an interface network. The interface network develops a gain control signal with a magnitude related to the magnitude of the restored sync pulse. The gain control signal is coupled to both sound and video gain control circuits for augmenting normal automatic gain control action with respect to sound and video signals. |
