Now let us show that a wavelet and its reverse have the same autocorrelation. Convolution is described as a folding operation between two signals. The autocorrelation of a signal is defined as the convolution of the signal with its zero-point reverse. Consider the wavelet (2, 1) in which the value 2 occurs at time 0. Its zero-point reverse is (1, 2) in which the value 2 occurs at time 0, so its autocorrelation table is
