ABSTRACT:
An electronically programmable oscillator has a plurality of digitally incremented selectable frequency signal outputs, providing a wide range of incrementally distinguishable, selectable frequencies having defined pulse widths. Incremental frequency selection is made through delay lines and bypassable interpolating delay lines connected in series. Selectable bypassable delay loops can be inserted into the oscillator signal path by manually controlled electronic, programmable selections. The width and shape of the pulse is regulated at several stages of the circuit, using solid state electronic components.
