Abstract: PURPOSE:The gate circuit is installed at input side of 1H-delay line, and is controlled only during burst period by supplying gate pulse. At the same time, the burst signal which is supplied to 1H-delay line is intercepted or reduced. Thus, picture quality deterioration can be prevented.

Abstract: PURPOSE:At the transmission side, the signal near maximum picture frequency is extracted and the carrier wave is modulated at this rising point. And at the reception side, the pulse is generated at changing point of carrier wave to be or-gated with the demodulation signal. Thus, transmission efficiency as well as reception picture quality can be increased.

Abstract: PURPOSE:To realize the extraction of the good signals with no reduction of the dynamic range by extracting the output of the CCD element via the complementary transitor which is controlled by the signal of the same phase as the charge transfer clock. CONSTITUTION:Clock phi1' of the same phase as clock phi1 among clocks phi1 and phi2 transferring the signals to capacitors C0, C1, C2, C3, C4 and so on of the CCD element is applied to the base of the complementary transistor formed with pnp transistor 12 and npn transistor 11 having the emitter connection via oscillator 13. The emitter of he complementary transistor is connected to capacitor C2 of the odd- numbered CCD element, and the pulse same as the transfer clock is supplied to capacitor C2. Thus no effect of the signal is given to C2, and also no reduction is caused to the effective level of the clock due to the base-emitter capacity in case the ordinary switching transistor is used. As a result, the signals can be extracted from collector 14 of transistor 11 in a good way.
