Title: Optical transmission method
Inventor: OSAKABE YOSHIO
IPC: H04B10/00
Filed: 1984-08-21
Abstract: PURPOSE:To eliminate transmission disturbance due to noise by applying FM modulation to a luminance signal and a synchronizing signal by a carrier wave including a high frequency signal, converting conversely a chrominance signal and a chrominance synchronizing signal into a signal occupying a low frequency band and applying FM modulation to a sound signal into a signal of an intermediate frequency. CONSTITUTION:A Y/C separation circuit 1 consists of low and high pass filters 2, 3 and separates a video signal into a luminance signal and a chrominance carrier wave signal. The luminance signal and the synchronizing signal from the filter 2 are modulated by an FM modulation circuit 4 by using a high frequency as a carrier wave. The chrominance carrier wave signal and the chrominance synchronizing signal from the filter 3 are subject to low frequency conversion by a low frequency conversion circuit 5. A sound signal is subject to FM modulation by FM modulation circuit 6. These signals are superimposed by a superimposing device 10 via high pass filters 7, 8, 9 and converted into an optical signal by an optical output device 11. A photoelectric converter 12 of the receiver receives an optical signal and separates the luminance signal, the sound signal and the low frequency conversion chrominance signal via extracting filters 13, 15. The separated signals are demodulated by demodulation circuits 16, 17, 19 of the next stage.

IPC: H03F3/16
Filed: 1983-09-22
Abstract: PURPOSE:To reduce the input capacity of a differential amplifier circuit and to make the operation of a semiconductor integrated circuit device high-speed by making the density of impurities of channels of FETs constituting a differential amplifier circuit lower than that of FETs of a source follower circuit. CONSTITUTION:When the voltage applied to a clock input terminal 3 is higher than the voltage of a reference voltage terminal 4, an FETQ11 is turned on, and the differential amplifier circuit consisting of FETs Q7 and Q8 is operated to make input signals from a set input terminal 8 and a reset input terminal 9 effective, and outputs corresponding to set and reset inputs are obtained in output terminals 6 and 7. Since the density of impurities of channels of FETs Q5- Q8, Q11, and Q12 constituting the differential amplifier circuit is lower than that of FETs Q13 and Q14 of the source follower circuit, the input capacity viewed from the clock input terminal 3, the set input terminal 8, and the reset input terminal 9 is small, and this device can be operated as a synchronous flip- flop in a high speed. As the result, the operation speed of the flip-flop is enhanced without increasing the power consumption.
