Abstract
Abstract Presented is a pulse generator that is selectively operable from an AC or a DC source of power. The pulse generator produces a pair of complementary DC coupled outputs. Pulse amplitude is continuously adjustable up to 10 volts, as are pulse width, from 50 nanoseconds to 20 milliseconds, and repetition rate from 1 hertz to 10 megahertz. Rise and fall times are typically 6 nanoseconds when the pulse generator feeds into a 50 ohm load. The pulse generator can feed almost any digital system; it directly drives resistor-transistor, diode-transistor and transitor-transistor logic circuits. From the viewpoint of organization, the apparatus comprises an oscillator, the output from which is connected to a delay control circuit, the output of which is divided into positive and negative going pulses channeled into a pair of output branch circuits. One branch feeds a width control circuit while the other branch feeds a differentiating network, the latter network functioning to provide a reference pulse for comparison with the complementary outputs from an amplifier connected to the two complementary output channels emanating from the width control circuit.
