VOLTAGE WAVEFORM GENERATOR

摘要

Voltage waveform generator including an integrator circuit and a source of reference voltage. Different resistances are connected in order in a series circuit between the source of reference voltage and the input to the integrator circuit to vary the rate at which the output voltage of the integrator circuit changes, thereby producing a desired output voltage waveform. Resistances are switched in and out of the series circuit as determined by the decoded output of a counter which counts periodic clock pulses. A feedback arrangement is coupled between the output and the input of the integrator circuit for restoring the integrator circuit to its starting condition prior to each period during which a waveform is produced.
