Abstract
A digital oscillator with output frequency accurately changeable from one period to the next. A plurality of retriggerable monostable multivibrators having discretely different design pulse widths are OR'd to an output monostable multivibrator having the narrowest design pulse width. The plurality of monostable multivibrators are triggered in common by the OR'd outputs thereof such that the longest pulse width one thereof defines the period of the output monostable multivibrator. Logic enabling means permit selection of multivibrator outputs to be OR'd.
