Abstract
A pulse generator for generating pulses having pulse edges at instants at which a varying amplitude input voltage is equal to one of at least two threshold values produced by a voltage source. The pulse generator has at least two voltage comparison circuits each having first and second outputs, first and second inputs for receiving voltages to be compared and third and fourth inputs for receiving blocking voltages applied thereto. The blocking voltages block the transmission of signals to the first and second comparison outputs of each voltage comparison circuit. One of the first or second inputs of each voltage comparison circuit is coupled to the pulse generator, while the other is coupled to the voltage source. The outputs of the voltage comparison circuits are coupled to each other and to the output of the pulse generator by diodes. The diodes connected to the first voltage comparison circuit are biased separately from those connected to the second voltage comparison circuit.
