Find 4-point DFT of x(n)={1,1,1,0} using radix-2 DIT-FFT
www.rcet.org.inCircular Convolution •The DFT is a sampled version of the Fourier transform, so multiplying DFTs corresponds to circular convolution •Circular convolution can be thought of as “time-domain aliasing” •If we want linear convolution, we must ensure time-limited input signals to avoid time-domain aliasing (like bandlimiting to

Circular Convolution - MIT OpenCourseWare
ocw.mit.eduThe L-point circular convolution of x1[n] and x2[n] is shown in OSB Figure 8.18(e), which can be formed by summing (b), (c), and (d) in the interval 0 ≤ n ≤ L − 1. Since the length of the linear convolution is (2L-1), the result of the 2L-point circular con volution in OSB Figure 8.18(f) is identical to the result of linear convolution.
