Abstract

PURPOSE: To omit the delay line at the video band and to minimize the size of the delay function circuit for the picture receiver which constitutes the IF band filter via the surface elastic wave filter, by delaying the luminance signal of one side only via the delay line formed by the elastic wave filter.
CONSTITUTION: The elastic surface filter is used to intermediate frequency band filter 2 containing output terminal 3 and 4 for the luminance and chrominance signal use which are connected to tuner circuit 1, and the desired IF band pass characteristics is given to filter 2. The delay time of terminal 3 to deliver the signal to luminance IF signal amplifier 5 is set longer than that of terminal 4 to deliver the signal to chrominance IF signal amplifier 8. And the difference of these delay time is set to the amount equivalent to the delay time of chrominance detector 9 and chrominance signal process circuit 10. At the same time, the output of amplifier 5 is processed by luminance detector 6 and luminance signal process circuit 7 and the delivered. Thus, the delay line used at the video band is omitted.
