Filed: 1987-05-07
Abstract: PURPOSE:To save power consumption by sensing a control signal so as to give an idling current to a class A or a class AB amplifier and inhibiting the flowing of the idling signal to the amplifier. CONSTITUTION:A control signal from a control signal generating circuit 14 is supplied to a switching drive circuit 18 via a coaxial cable 31, a low pass filter 16 and a detecting circuit 17 to turn on a switch 19. Thus, an idling current flows to the class A or AB class amplifying circuit 21. Then a transmission signal from a transmission signal generating circuit 11 is amplified by the amplifier 21 and sent. When the control signal from the control signal generating circuit 14 is lost, the switch 19 is turned off and no idling current to the amplifier 21 flows.

IPC: H04N5/208
Filed: 1991-05-16
Abstract: PURPOSE:To output a clear picture by preparing the contour correction signal at the two frequency bands by multiplying the two contour signals and freely controlling the positive and negative contours. CONSTITUTION:A first contour signal generation circuit 1a generates a first waveform contour signal and inputs this in one of a multiplying circuit 1e. A second contour generation circuit 1b generates the second contour signal using a passive element and this is inputted in a half-wave circuit 1c. Then, the contour signal on the black side outputted from the half-wave circuit 1c is inputted in the other multiplying circuit 1e. In this case, the output signal from the half-wave circuit 1c becomes the multiplying by the negative side part of the first contour signal as the contour signal on the only negative side exists, the output becomes the component of the sum and difference of the frequency band of the two contour signals and the specific waveform signal is outputted. Therefore, the output contour correction signal of this whole contour correction circuit becomes a thin signal on the positive side and a thick and large signal on the negative side.
