I need help with this :

I have a transfert function and I want to know the numerical value of the output if the input is a square wave of 1Vpp , duty cycle of 50% and a frequency of 20KhZ

My guess would be to start with H(s) = Vout/Vin

Vout = Vin*H(s) and put s = (20k*2pi*i), but wut do with Vin? do I use Vrms=0.5 and thats it?

take the fourier series of the square wave and multiply the result with the transfer function

But that doesnt give me a numerical value , does it? Its still dependant on t as i have

f(t) = sum[ 4/pi[sin(2pi*n*t/T)] ]

the fourier coefficients are given to you in the equation you just wrote. just multiply those with the corresponding frequencies and you're done. however, i take it that i might have to explain more but ill let u think about it first.

lol lebs dumb as fuk

lmao wat a fagget



I'm not exactly familiar with the behavior of the fourier series, i know that a given time it can either be -0.5V or 5V. My guess would be to take my vin as Vpp = 1v, but i'm not entirely sure. any tips?
