IncorrectLet be a discrete-time signal whose -transform is .
Which of the following statements is/are TRUE?
The discrete-time Fourier transform (DTFT) of always exists
The region of convergence (RoC) of contains neither poles nor zeros
The discrete-time Fourier transform (DTFT) exists if the region of convergence (RoC) contains the unit circle
If , where is the unit impulse and is a scalar, then the region of convergence is the entire -plane
