Fundamentals and Instruments 889associated with many of the common gain/frequency characteristics or design or
performance problems.
The other types of waveform that can be provided by a function generator have specifi c
applications. The sinewave output, although too poor in linearity to allow amplifi er
THD measurements to be made with any accuracy, is usually quite free from amplitude
variation, and the “ single knob ” wide-range frequency control of such an instrument
