Help with Riesz basis (see attached), please show all work

Consider the function p (t ) = 1, -Ists1 10, It | > 1, and set V = Span ({p(t - n)}nez). Is {o(t - n) }nez a Riesz basis for V? Circle one: YES or NO Justification: [HINT: There are multiple approaches to this problem. One approach is to consider the signal given by IN (t ) = [(-1)" p(t - n), n=0 where N > 0 is fixed. Recall that by definition, for {p(t-n) }nez a Riesz basis for V, there must be constants A, B > 0 such that A [lan ? s [ anpn (t ) S B Clan ? . n=1 n= 1 n=1 What does ry (t) tell us about A in this case?]
