Question: Consider a system represented by the convolution sum (a) Obtain the BIBO stability condition for this system, assuming that the input x[m, n] is bounded.

Consider a system represented by the convolution sum

| yim, n] ΣΣ hm-L,n- qrk, k=0 €=-k


(a) Obtain the BIBO stability condition for this system, assuming that the input x[m, n] is bounded.

(b) Use the variable transformation

т


to obtain the BIBO stability condition when x[m, n] is exactly the same as before. Is this condition equivalent to the previous? Explain.
