As an example, in the design of a 4-bit ripple carry adder, the second and fourth full adders do not use output inverters for carry generation. one inverter delay is eliminated for every two full adders in the adder chain, and four transistors are reduced. Similarly, in complex designs like the multiplier, the output inverters for generating sum and carry can be used in alternative stages, thereby improving speed and reducing area.

例如，在4位行波进位加法器中，第2级和第4级的加法器不需要用输出反向器进行进位产生，因此，加法器链上的反向器延迟每两级全加器抵消一次，因此可以减少4个晶体管，类似的，在乘法器这样的复杂设计中，用于产生"和"以及"进位"的输出反向器可以用于其它方面，因此可以改善电路的速度和减小面积。
