Impulse Response and Convolution
Impulse Response A CT system is completely characterized by its impulse response, much as a DT system is completely characterized by its unit-sample response. We have worked with the impulse (Dirac delta) function δ(t) previously. It’s de ned in a limit as follows. Let p ∆(t) represent a pulse of width ∆ and height 1 ∆ so that its area ...

Discrete Fourier Transform
sigproc.mit.eduFourier transforms have no periodicity constaint: X(Ω) = X∞ n=−∞ x[n]e−jΩn (summed over all samples n) but are functions of continuous domain (Ω). →not convenient for numerical computations Discrete Fourier Transform: discrete frequencies for aperiodic signals.
