For example, if the third tap of the initial circuit performs a multiply by thirteen operation , and all of the other taps multiply by numbers that are powers of two, then the reference delay unit 205 of the final circuit should be set to provide a delay of {HEAD ~ three unit time periods}, since the multiply operation for {TAIL ~ the third tap} of the initial circuit would require the most amount of hardware to implement
