A NEGATIVE CLAMPER will clamp the upper extremity of the input waveform to a dc potential
of 0 volts.
A COMMON-BASE TRANSISTOR CLAMPER clamps the collector voltage to a reference level.
A waveform other than a sine wave is called a COMPLEX WAVE.
If the odd harmonics of a sine wave are added algebraically, the result is a square wave. A
PERFECT SQUARE WAVE is composed of an infinite number of odd harmonics in phase with the
