Thanks in advance...
A 50 V rms carrier is modulated by a square wave = 4V/pi ( sin wt + 1/3 sin 3wt + 1/5 sin 5wt + .. ) if the 1st 4 harmonics are considered then find Meff ?? if V = 20 v ?
I tried to use the m = Ei / Ec formula for each of the harmonics but the ans is still coming wrong . .
The correct ans...
