Abstract
PURPOSE: To avoid occurrence of the phase distortion and then to solve the buzz of the aural signal by supplying the tuner's output to the BPF featuring such characteristics in that the range where the double side-band wave centering on the video carrier frequency exists is flat.
CONSTITUTION: The color TV signal received through antenna 1 is supplied to mixer 3 via high-frequency amplifier 2 and then supplied to the video intermedium frequency amplifier via BPF5 after the frequency conversion. The signal sent from amplifier 6 is supplied to multiplier 7 as well as limiter 9 via BPF8, and the carrier of this output is supplied to multiplier 7. The output of 7 is supplied to correction filter 10. BPF5 features such characteristics in that the range where the double side-band wave centering on the video carrier frequency exists is flat, and as a result the amplitude distortion and the phase distortion can be eliminated. However, this output features the amplitude of the low-range band whose level is double as high as other band component. Thus the detection output is corrected by filter 10 featuring the frequency characteristics in that the amplitude of the low-range component is 1/2 the other band amplitude.
