Homework Statement
My message signal is the Fourier Series (x(t)) of a bipolar pulse. This signal passes through the ideal low pass filter, h(f), which has a cutoff frequency of 4Khz. What the baseband bandwidth of the filtered signal?
Homework Equations
ƩAn*cos(2*pi*n*f0*t), An= [4*(-1)^((n-1)/2)]/(pi*n)
In other words: x(t)=(4/pi)*[cos(2*pi*f0*t)-(1/3)*cos(2*pi*3*f0*t)+(1/5)*cos(2*pi*5*f0*t)]
The Attempt at a Solution
I don't know if I should apply the Fourier Transform to the Fourier Series because this one is x(t) and my filter is h(f). What should I do?
