WebThe DTFS coefficients of x3_all[n] in one period can be translated to the DTFS coefficients of x3[n] in one period. Therefore x3[n] = x3_all[n]. We’ve already had the conclusion that x3[n] is purely real, thus x3_all is also real.WebFor the CTFS, the signal x(t) has a period of T, fundamental frequency ! ... 0 = 2ˇ=T; for the DTFS, the signal x[n] has a period of N, fundamental frequency 0 = 2ˇ=N. a k and b k denote the Fourier coe cients of x(t) (or x[n]) and y(t) (or y[n]) respectively. 2. Periodic convolutions can be evaluated by summing or integrating over any single ...

</n>WebExistence of DTFS Unlike the existence of CTFS, the existence of DTFS is straightforward since it involves finite series. Hence the DTFS representation exists for all finite-valued periodic DT signals. Let’s now summarize the DTFS representation and compare & contrast with CTFS representation: x[n] = ∑ k= <n>
