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.

During the early months of 2009, some economists concluded that the slew of U.S. government programs created during the fall of 2008 to stabilize an economy marked by an absence of credit, a wave of enormous asset write downs, a precipitous decline in housing prices, and a historic loss of consumer confidence _________________ has not succeeded in engendering healthy intra-bank credit flows and reviving depressed equity prices has not succeeded in engendering healthy intra-bank credit flows and bringing about the revival of have not succeeded in engendering healthy intra-bank credit flows and reviving depressed equity prices have not succeeded in engendering healthy intra-bank credit flows and to revive depressed equity prices
