Question:
A discrete-time signal x(n) is defined as
(a) Determine its values and sketch the signal x(n).
(b) Sketch the signals that result if we:
(1) First fold x(n) and then delay the resulting signal by four samples.
(2) First delay x(n) by four samples and then fold the resulting signal.
(c) Sketch the signal x(-n + 4).
(d) Compare the result in parts (b) and (c) and derive a rule for obtaining the signal x(-n + k) from x(n).
(e) Can you express the signal x(n) in terms of signals δ(n) and u(n)?
