摘要: Apparatus for use with a television receiver selectively inhibiting reception of broadcast signals. The apparatus includes number signal generating circuits, each respectively set to generate an electrical substantially equal the carrier frequency corresponding signal, and timer capable being preset activate deactivate selected oscillators on timed basis. circuits are coupled antenna input leads so that when activated signals produced thereby cause sufficient interference incoming effectively block reception.
