The length-8 input signal n8 7 6 5 43 21is applied to the input of the FIR filter y[n] = x[n-2] The circular buffer version of the sample processing implementation of the delay operation requires the use of a 3-dimensional linear buffer array of internal states WWo W1 2 and a pointer p circulating over w (a) Make a table of the numerical values of the contents of the array w for the successive time instants 0
