VIDEO DISPLAY AND DEFLECTING DEVICE
Document Type and Number:
Japanese Patent JPH0670185
Kind Code:
A
Abstract:
PURPOSE: To easily change the length or inclination of the retrace part of the vertical saw-tooth wave signal by inputting digital data. CONSTITUTION: A D/A converter 16 D/A converts a digital data input supplied from a microprocessor 17 and generates a voltage VRSLOPE. A V/I converter 15 converts the voltage VRSLOPE to a current IDRAMP. The current IDRAMP forms the retrace part of the vertical saw-tooth wave signal VRAMP and a current IURAMP generated by a V/I converter 21 forms the trace part of the saw-tooth wave signal VRAMP. Terminals 18a and 18b of a capacitor 14 are respectively connected to the inverted input terminal and output terminal of an amplifier 18 and form a current integrator. The amplifier 18 generates the saw-tooth wave signal VRAMP.
