Abstract

AN ANTENNA BOOSTER-MIXER CIRCUIT (2) IS INCORPORATED INTO A VTR (VIDEO TAPE RECORDER) (1) AND COMPRISES AN ANTENNA INPUT TERMINAL(14), AN ANTENNA OUTPUT TERMINAL (15), AT LEAST ONE BOOSTER AMPLIFIER (7,9) WHICH IS ELECTRICALLY CONNECTED BETWEEN THE ANTENNA INPUT TERMINAL (14) AND THE ANTENNA OUTPUT TERMINAL (15) AND USES A POWER SUPPLY IN COMMON WITH THE VTR (1), AND A SIGNAL BY-PASS CIRCUIT (12) ELECTRICALLY CONNECTED IN PARALLEL WITH THE BOOSTER AMPLIFIER (7,9). WHEN THE POWER SUPPLY FOR THE VTR (1) IS TURNED ON UPON SIGNAL RECORDING OR REPRODUCTION, A RECEIVED SIGNAL SUPPLIED TO THE ANTENNA INPUT TERMINAL (14) IS TRANSMITTED FROM THE BOOSTER AMPLIFIER (7,9) TO THE ANTENNA OUTPUT TERMINAL (15). WHEN THE POWER SUPPLY FOR THE VTR (1) IS TURNED OFF, THE RECEIVED SIGNAL SUPPLIED TO THE ANTENNA INPUT TERMINAL (14) IS OUTPUTTED FROM THE ANTENNA OUTPUT TERMINAL (15) THROUGH THE SIGNAL BY-PASS CIRCUIT (12). OWING TO THE ABOVE CONSTRUCTION, THE ANTENNA BOOSTER-MIXER CIRCUIT (2) CAN BE PROVIDED WHICH BYPASSES THE RECEIVED SIGNAL INPUT TO THE ANTENNA INPUT TERMINAL (14) SO AS TO BE OUTPUT TO THE ANTENNA OUTPUT TERMINAL (15) AND PREVENTS UNNECESSARY POWER CONSUMPTION EVEN IN THE CASE WHERE THE VTR (1) IS TURNED OFF TO DEACTIVATE THE BOOSTER AMPLIFIER (7,9).
