load h(0), h(2), h(4), h(6)
flops corresponding to h(0), h(2), h(4) and h(6) are enabled. This produces
the temporary output, y
output, y(n). The following shows what the overall output, y(n), equals:
This is identical to the output of the 8-tap filter shown in
cycle 1, this process is repeated at every cycle.
