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:

DB | = | ||

= | |||

= |

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.
