    Relationship between z-transform and DTFT

    Re: z-transform and DTFT In case of DTFT of a system function, it can do the transform only if the h[n] is a stable sequence Σh[n] should be less than infinite. So we can take DTFT only for stable systems. But by using z-transform we can transform even the unstable systems and can analysis...

    What is the meaning of angle in a fourier transformed signal?

    Re: fourier transform Phase : arises from phasor . Phasor is something like a vector which is rotating (changing its angle instantaneously) so the angle it substends at present with respect to a reference phasor is the phase angle. Now The importance of Fourier Transform: [this is my own...
