Induced voltage=4.44*f*N*A*B = 4*form factor*f*N*A*B
f=freq
N=no of primary turns
A=area of wdg
B=max flux density

For sinusoidal input, form factor= 1.1 , its a peaky wave
form

But for square ac input signal, form factor is less than
1.1. (as its non peaky)

So other factors remaining same, induced voltage decreases
for square input ac signal.
