With these points in mind, if the impulse response characteristics of the initial circuit performs a given multiplication operation with {HEAD ~ a coefficient} that necessitates the use of an extensive amount of hardware, the tap number corresponding to that multiplication operation should generally be selected as the integer delay period for the reference delay unit 205 in {TAIL ~ the final circuit}
