In mathematics, a Dirac comb (also known as shah function, impulse train or sampling function) is a periodic function with the formula The symbol , where the period is omitted, represents a Dirac comb of unit period. This implies Because the Dirac comb function is periodic, it can be represented as a Fourier …

The distance between the lines is given by 1/ PRI and is 100 MHz. … WebSep 8, 2016 · Now, an impulse train is periodic and discrete, so its Fourier transform must be discrete (due to periodicity in time) and periodic (due to discretization in time), which …
WebDTFT of Periodic Impulse Train Now consider the periodic discrete-time impulse train sequence p~[n] = X1 r=1 [n rN]: Observe that this is like x[n] = 1 upsampled by N, i.e., there are N 1 zeros inserted between each pair of samples in x[n]. Recall that integer upsampling by a factor of Njust squeezes the spectrum such that P~(ej!) = X(ej!N ...
