Question:

The discretized approximation of a pulse is given by

1 -N/4 <n <-1 -1 1<n<(N/4) +1 w(nTs) = 0 otherwise


where N = 10000 and Ts = 0:001 seconds.

(a) Obtain this signal and let the plotted signal using plot be the analog signal. Determine the duration of the analog signal.

(b) There are two possible ways to visualize the shifting of an analog signal. Since when advancing or delaying a signal the values of the signal remain the same, it is only the time values that change we could visualize a shift by changing the time scale to be a shifted version of the original scale. Using this approach plot the shifted signal w(t - 2).

(c) The other way to visualize the time shifting is to obtain the values of the shifted signal and plot it against the original time support. This way we could continue processing the signal while with the previous approach we can only visualize it. Using this approach obtain w(t - 2) and then plot it.

(d) Obtain the scaled and shifted approximations to w(1.5t) and w(1.5t - 2) using our function scale shift and comment on your results.
