Q1:

A sine wave is passed through an amplifier which severely limits it symmetrically. If then passes to a second amplifier which is narrow band and tuned to the frequency of the original sine wave. What will be the output wave from this second amplifier?

A A square wave of the same frequency as that of the original sine wave

B A square wave of double the frequency of that of original sine wave

C A sine wave of constant amplitude at the frequency of the original sine wave

D A sine wave of constant amplitude at double frequency of the original sine wave

ANS:C - A sine wave of constant amplitude at the frequency of the original sine wave
