Description: Drawn to meet the difference equation: y [n]-1.25y [n-1]+ 0.75y [n-2]-0.125y [n-3] = x [n]+ 0.5x [n-1], discrete-time signal X [n] the bilateral z transform is the promotion of discrete Fourier transform, and discrete-time Fourier transform in the study of discrete-time signal and the system would be very useful.
