Discrete-time Fourier Transform - Relationship To The Z-transform

Relationship To The Z-transform

The DTFT is a special case of the Z-transform. The bilateral Z-transform is defined as:

So the special case is . Since, it is the evaluation of the Z-transform around the unit circle in the complex plane.

Famous quotes containing the word relationship:

    “Only men of moral and mental force, of a patriotic regard for the relationship of the two races, can be of real service as ministers in the South. Less theology and more of human brotherhood, less declamation and more common sense and love for truth, must be the qualifications of the new ministry that shall yet save the race from the evils of false teaching.”
    —Fannie Barrier Williams (1855–1944)
