15 points The signal y t is generated by convolving a band limited signal x1 t with another bandlimited signal x2 t that is y t x1 t x2 t Where frequency responses of x1 t and x2 t are expressed as X1 w 0 for lw 1000m and X2 w 0 for w 2000 respectively Impulse train sampling is performed on y t to obtain 00 y t y nT 8 t nT 111 00 Specify the range of values for the sampling period T which ensures that y t is recoverable from y t
