(a) Let x(n) = u(n) Find ya (n) by first convolving x(n) with h1 (n) and then convolving the result with h2 (n) ie ya(n) = x(n) * h1 (n) * h2 (n) (b) Again let x(n) = u(n) Find yb(n) by convolving x(n) with the result of the convolution of h1 (n) and h2 (n) ie yb(n) = x(n) * h1(n) * h2(n) Your results for parts (a) and (b) should be identical, illustrating.

Eq1) The utility of this frequency domain function is rooted in the Poisson summation formula Let X (f) be the Fourier transform of any function, x (t) , whose samples at some interval T (seconds) are equal (or proportional) to the x n sequence, ie T ⋅ x (nT) = x n Then the periodic function represented by the Fourier series is a periodic summation of X (f) in terms of frequency f. Term (secular) trend We can discern the longterm trend by smoothing or averaging the past N values of the variable For the stock market average, we may consider a 5day moving average yn to be the mean of the past 5 days’ market closing values xn;xn 1;.

May 16, 15 · The answer to this (and your other similar question) is most likely found in the somewhat unusual notation used for the system In ordinary terms, if you just take your system as a map between input and output signal, then you're absolutely right, it would not be time invariant.
