Granted: 1990-10-08
Abstract: Thr R-2R type D/A converter comprises two series circuit each comprising a resistor and a switch. One series circuit is connected between one end of a ladder resistor circuit and the ground. The other series circuit is connected between the other end of the ladder resistor circuit and the ground. The switches in the series circuits are selectively turned on/off, so that an output signal may be supplied in either direction. Analog circuits are connected one to each terminal of the R-2R type D/A converter circuit. By turning on/ off the switches of the circuits, a D/A converter output signal may be supplied selectively to either analog circuit. Since the switches of the series circuits are not located in the analog signal line, the D/A converted output signal can be supplied selectively to the two analog circuits.

Abstract: In the image signal processing of VTR, the system detects the positive and  negative  edge  (1,2)  by  the  input  of  VTR  head switch-pulse. The digital signal processing  section  comprises  a counter block (3) for  counting  20H  period  from  the  start  of positive and negative edges (1,2), a gate pulse generator (4)  for generating the pulse for 2H period. The system  includes  a  level demodulation block (6) for detecting each level in accordance with copy preventing signal from the analog section,  a  signal  killer block (9) for controlling the output of image processing signal by the detected signal from the block (6).
