The exponential Fourier series of a certain periodic signal is given as:
f(t) = (2+j2) exp(-j300t) + j2 exp(-j10t) +3 - j2 exp(j10t) + (2-j2) exp(j300t)
a. Find the compact trigonometric Fourier series of f(t).
b. Find the bandwidth of the signal.
c. Find the Fourier Transform of f(t).
d. Design a simple low pass filter (RC circuit) that reduces the amplitude of the highest
frequency part of f(t) by at least 50%. Write down its H(ω) and plot its spectrum.
e. Plot the spectrum of f(t) (i.e. F(ω) before and after passing through the low pass filter.
