The first signal operation we investigate is amplitude scaling. Consider the discrete-time signal x[k] and constant c. The discrete-time signal y[k] = cx[k] is an "amplitude scaled" version of x[k] since every value in the original discrete-time signal x[k] has been scaled by a factor "c".
This video shows several examples of performing amplitude scaling. Specifically, given an initial discrete-time signal x[k] we also compute and plot the signals 2x[k] and -x[k].
