ABSTRACT:
There is disclosed circuitry for developing ramp type signals such as sawtooth waveforms, triangular waveforms, etc. The circuitry comprises an oscillator which supplies an oscillating signal to an up/down binary counter which counts occurrences of said signal. The binary output of the counter is converted into an analog signal and supplied to an output buffer stage. An offset control is associated with the output stage whereby an offset may be introduced into the output signal produced by the output stage. A strobe control is also associated with the output stage for providing selective transmission of the output signal of the stage to an output terminal in accordance with a strobe control signal applied to the output stage. The strobe control signal and the offset control signal determine the output signal waveform shape. Circuitry is also provided with the capability of greatly increasing the normal frequency of the oscillator for correspondingly reducing the time required for diagnostic testing of the circuitry.
