The definition of variance of a random variable: $$Var(X)=E[(X-E(X))^2]$$ Since the variable was defined to have mean zero: $$E(X)=0$$ Inputting that into the formula, you get: $$E(X^2)$$ The ...

This is a statistics question and should not be asked here. But I will try to answer the question as best as I can (it won't be the best answer). First off, I don't see what the phenomenon you are ...

$$\large \text{FOURIER TRANSFORMS}$$ Fourier series $X[k]$: $$\large X[k] = \int_{0}^{T}x(t)e^{\huge \frac{-j2\pi kt}{T}}dt$$ $T$ = Length of the window or fundamental oscillation, $\large \frac{1}{T}... View answer 1 votes Frequency response is the Fourier transform (or DFT in discrete case) of the impulse response. I think you may be confusing frequency response with frequency domain representation of a signal. ... View answer Accepted answer 1 votes Your question is fairly broad, let me answer it step by step. First of all$H(s)\$ is indeed called the transfer function, and is the laplace transform of the impulse response. It's useful for ...

The example sounds like pitch tracking combined with comb filtering. Using method like this could be implemented by "drawing" as well, as in SPEAR analysis and re-synthesis program. If the vocal is ...

If I understand the question correctly, this result may be of help. Keeping in mind that amplitude modulation is convolution in frequency domain. All you need to do then is convolve the unit impulse ...
