Abstract
PURPOSE: To sharpen the TV picture, by detecting the running speed of a mobile body, changing the time constant of AGC for the reception system with the detection signal, and preventing the flicker of automobile inder running.
CONSTITUTION: The reception signal from the antennas 1a and 1b is picked up with the selection circuit 2 after selection and it is fed to the detection circuit 5 via the tuner 3 and the IF amplifier 4. Further, the output signal from the detection circuit 5 is fed to the peak detection circuit 7 to detect the level of the output signal, and this signal is fed to the time constant circuit 8. Further, the signal such as noise detected from the loop antenna 9 is fed to the time constant circuit 8 via the amplifier 10, wave shape circuit 11, and integration circuit 12. Further, the AGC signal from the time constant circuit 8 is fed to the level detection circuit 15 via the time constant circuit 14 to detect that the AGC signal is less than a given level, and this signal is fed to the FF circuit 16 and the control signal from the output of the circuit 16 is fed to the selection circuit 2, allowing to prevent the flicker caused by the running of automobile.
