Circular linear correlation
WebCircular-circular correlation picks up more interesting patterns than circular-linear correlation. In circiular-linear correlation, the linear variable is implied to follow a sinusoidal pattern. … For example, when the phase shift is pi/2, the two variables have a correlation of zero. How do you find circular convolution using DFT and Idft?
