Title:
DRIVER CIRCUIT WITH MEANS FOR COMPENSATING TRANSMISSION LINE LOSS
Document Type and Number:
Japanese Patent JP3509258
Kind Code:
B2
Abstract:
PURPOSE: To compensate optional transmission line loss by adding a square wave and a triangular wave to an original wave.
CONSTITUTION: This circuit is provided with a signal generator 1, a register 2 storing square pulse width data and oscillation data, square wave generators 3 to 5 generating square waves in accordance with pulse width data and oscillation data stored in the register 2, an adder 6 adding an output 1a from the signal generator and outputs 3a to 5a from the respective square wave generators 3 to 5, and an amplifier circuit 7 amplifying an output 6a from the adder 6. Thus the circuit adds a square wave pulse to a signal waveform so as to compensate the transmission circuit loss.
