A finite-length signal x[n] is nonzero in the interval 0 ≤ n ≤ 19. This signal is the input to the system shown in Figure P9.10, where

The output of the system, y[n], for the interval n = 19, . . . , 28 can be expressed in terms of the DTFT X(e^jω) for appropriate values of ω. Write an expression for y[n] in this interval in terms of X(e^jω).
