Square Wave Input: For
We now examine what happens when
For
our output due to a sine wave input becomes:
For a square wave input expressed as the sum of a series
of sinusoidal inputs the output becomes:
We thus expect the output due to a square wave input to be about 1.052
times the output due to a sine wave input. Expressed in decibels this becomes:
The output due to a square wave input is about 0.44 DB greater
than it would be for a sine wave input when
We may conclude that the difference in response between
a sine wave input and a square wave input is small. Thus,
to experimentally determine the unknown parameter B we may
use square waves of various frequencies and analyze the results
the same as we would for a sine wave input.
