I have a question which is to design a filter of the form: y(n) = a(0)x(n) + a(1)x(n-1) + a(2)x(n-2) to remove a narrowband disturbance with frequency f0 = 70Hz. The sampling frequency, fs is 280Hz. I've made an attempt at answering it, but don't think my result is correct: w0 = (2*pi)*...

I have a practice question, which is to find the Fourier Transform of cos(2^pi^t) By substitution into the FT formula, and use of eulers formula,I have managed to reduced to: INTEGRALOF ( (cos(2*pi*t) * ( cos(2*pi*F*t) - j*sin(2*pi*F*t) ) ) By plotting the frequency graph of the...
