The modulus or magnitude of a complex number ( denoted by ∣z∣ ), is the distance between the origin and that number. If the z = a +bi is a complex number than the modulus is. ∣z∣ = a2 +b2. Example 01: Find the modulus of z = 6 +3i. In this example a = 6 and b = 3, so the modulus is:

$\begingroup$ @StanleyPawlukiewicz No it would not. Existance of Fourier transform does not imply existance of Z-transform, but the converse is true; i.e., existance of Z-transform (may) imply existing of Fourier transform (which is found by evaluating Z-transform on the unit circle) which requires that ROC includes unit circle.inverse z-transform calculator.
