Homework Help: Discrete-time signal through a PAM

  1. Aug 23, 2010 #1
    A discrete-time signal x[n] is filtered through a PAM p(t). The shapes of these signals are described in the attached image.

    i) Calculate and plot the output y(t) from this pulse amplitude modulation.
    ii) Let y[n])=y(nTs) be the sampled signal of y(t). Calculate and plot y[n]
    iii) Determine a general connection between x[n] and y[n], which is valid for any arbitrary x[n]

    I have only tried my luck on i) but gets stuck at the plotting. Anyone with a better knowledge of how to solve this problem?

    Kind regards, Christian
