A Transistorized Four-Quadrant Time-Division Multiplier with an Accuracy of 0.1 Per Cent

This article describes a four-quadrant time-division multiplier with an over-all accuracy of better than 0.1 per cent of full scale. The circuit is independent of the transistor characteristics, requires no complicated balancing adjustments, exhibits excellent stability and uses only simple, noncritical circuitry. The maximum output voltage is 10 v when both input voltages are 10 v.
