SUMMARY
The discussion centers on computing the Discrete-Time Fourier Transform (DTFT) of the signal x[n] = (0.8)^n u[n]. Participants highlight the need to utilize DTFT properties to derive the transform, as the specific DTFT pair for (0.8)^n is not readily available in standard tables. The reference provided is a PDF containing DTFT pairs, specifically noting page 20 for relevant information. The consensus is that deriving the DTFT using known properties is essential for solving the problem.
