universal waveform generator.

(a) Sawtooth

and

asymmetrical triangle waveforms; both

are

generally provided

by the

more versatile type

of

function

generator.

The

sawtooth

and the

triangular wave (Figure

9.6) can

both

be

considered

as

limiting cases

of

the asymmetrical

triangular wave.

but complementary voltage waveform generators

such

as
