I have a noisy signal a on which I've performed a Fourier transform (A = fft(a)). The original signal has a frequency of 2 Hz.
I'm supposed to remove the noise by multiplying by a Gaussian function,
gaussian = exp(-(abs(v) - 2)**2)/(2*(0.5**2))
where v is a frequency in Hz. What am I supposed to use for v? A single number? Some span of values?
