Abstract
A counter is provided to count pulses applied thereto, with the output of the counter being applied to decode circuitry which operates selection or switching circuits to connect a plurality of pulse sources, each at a different repetition rate or frequency, to the counter in a predetermined sequence and at the occurrence of predetermined counts in said counter. The desired function of time being generated is represented by the magnitude of the digital binary number in the counter.
Claims6
A digital function generator comprising:
- (a) a counter having an input for receiving pulses to be counted and a plurality of outputs;
- (b) switching means having a plurality of pulse inputs connected to receive pulses thereon with the pulses having a different repetition rate on each of the different inputs, an output, and a plurality of selection inputs for coupling a selected pulse input to the output in response to a signal applied to a specific selection input, the output being further connected to the input of said counter;
- and
- (c) decode means having a plurality of inputs connected to the plurality of outputs of said counter and a plurality of outputs connected to the plurality of selection inputs of said switching means for providing signals on the selection inputs in a predetermined sequence and at the occurrence of predetermined counts in said counter.
