Discrete-Time Fourier Transform of Impulse

11/26/14

Running Time: 3:22

This example computes the Discrete-Time Fourier Transform (DTFT) of the discrete-time signal x[k] using the definition of the DTFT.  The signal x[k] is a single impulse located at time k = n0.

Discrete-Time Fourier Transform of Decaying Exponential

11/26/14

Running Time: 5:00

This example computes the Discrete-Time Fourier Transform (DTFT) of the discrete-time signal x[k] using the definition of the DTFT.  The signal x[k] is a decaying exponential signal.
