In many kinds of equipment, it is important to produce and
readily control accurate waveforms of various frequencies and
profiles. Examples include agile frequency sources with low phase
noise and low spurious signal content for communications, and
simply generated frequency stimuli for industrial and biomedical
applications. In such applications, the ability to generate an
adjustable waveform conveniently and cost effectively is a key
design consideration.
