Abstract: PURPOSE:To obtain a correct quantized binary signal through a simple circuit and without impairing the effective function of a quantizing system, by detecting the break of characters and thus compensating the broken part of the character from the white signal to a black one. CONSTITUTION:The analog video signal is delayed by a certain time through the analog delay circuit 102, and the value obtained by multiplying the maximum value of the delay output by a constant is applied to the register 106. Using this value for the slice level, the analog signal is converted into a binary coded signal to be applied to the binary coded signal compensating circuit 211. At the same time, a sudden increase of the slice level is detected by the sudden increase detection circuit 207, and a sudden drop of the slice level is detected by the sudden drop detection circuit 208 respectively. Then the detection signal is applied to the ROM circuit 210. The quantized signal delivered from the register 106 is delayed by the digital shift register 209, and this delayed output is applied to the circuit 210. Then the broken part of the character is decided by the circuit 210, and the signal which compensates the white signal into a black one is applied to the circuit 211. Thus a correct quantized binary signal is delivered.

Filed: 1995-01-25
Abstract: PURPOSE: To make the operation stable by controlling the amplitude of a carrier signal waveform only with a resistive component so as to enhance the immunity against environmental change such as the fluctuation of temperature and power supply. CONSTITUTION: I, Qch differential coding signals from a differential logic section 1 are respectively given to an attenuator drive section 5 as addresses to read waveform pattern data stored in a ROM of attenuation drive circuits 50, 51 and the data are fed to step attenuators 40, 41 provided to an orthogonal modulation section 3 as a control signal. Each of the attenuators 40, 41 is made up of plural resistors in cascade connection and switches each provided across each resistor and the resistance is decided by combinations of the resistors. The signal from the local oscillator 4 is attenuated so as to be close to waveform pattern data read from the ROM by operating the switch with a control signal from the attenuation drive circuits 50, 51 to control the amplitude and to provide an output.  Thus, even when a diode is employed for each switch, the circuit is stably operated independently of fluctuation of the resistance of the diode owing to temperature.
