Lecture 5: Z transform - MIT OpenCourseWare
ocw.mit.eduZ Transform. We call the relation between. H (z) and. h [n] the. Z. transform. H (z) = h [n] z. − . n. n. Z transform maps a function of discrete time. n. to a function of. z. Although motivated by system functions, we can define a Z trans form for any signal. X (z) = x [n] z. − n n =−∞ Notice that we include n< 0 as well as n> 0 ...
