Which of the following choices meets the minimum requirement needed to create specialized waveforms that are used in digital control and sequencing circuits?

ANS:A - basic gates, a clock oscillator, and a repetitive waveform generator

Specialized waveform are additional feature added in function generators there maximum output frequency will often be much less than the typical sine and square wave frequencies available from the generator.

Function generator contains a electronic oscillator which generates repetitive waveform.
