How can we handle the issue of acoustic echo cancellation and active noise compensation by a single adaptive system identification framework?

In general adaptive time-varying filters are used for acoustic echo cancellation (AEC) and active noise suppression. In non-linear AEC we assume there is low or no noise when cancel the echo with...

Why a discrete time signal when converted to frequency domain using DTFT or DFT is continuous? Any mathematical proof behind it?

Let x(n) is a discrete time signal. We have done the Discrete Fourier Transform of it. Then the spectrum we get in frequency domain is continuous. How it happens?
