Abstract

PURPOSE:To elevate a characteristic of a comb line filter, by supplying a charge coupled device (CCD) driving pulse from a clock driver driven by a complementary pulse obtained by driving an FF by making a pulse whose polarity is opposite to a sampling pulse its trigger source. CONSTITUTION:A pulse which has sampled a master clock pulse CI every other period, and pulses N7, N9 formed like a comb are supplied to a reset type FF consisting of NOR gates 25, 26, and complementary pulses N8, N10 of nearly 50% duty are obtained. An opposite polarity pulse N11 of a pulse N8 is generated by an invertor 27 of a clock driver CD1, and a CCD driving pulse P1 is obtained by driving a pushpull circuit consisting of MOSFETs M7, M8 by complementary pulses N12, N13 generated by buffer circuits 28, 29. On the other hand, the pulse N10 is inputted to a clock driver CD2, and a CCD driving pulse P2 is obtained in the same way.
