Supply the missing information for each diagram.

A.


B.


C.


D.

A. From the figure, it is evident that the input is 5cm and the output is 5cm. = 1. Therefore, it is a (x1) repeater.


B. From the figure, it is evident that the input is 3cm and the output is 15cm. = 5. Therefore, it is a (x5) repeater.


C. From the figure, it is evident that the input is 1.25cm and the repeater is a (x4). = 4, gives Output = 1.25x4 = 5cm.


D. From the figure, it is evident that the output is 36cm and the repeater is a (x4) and a (x3) = (x12). = 12, gives Input = = 3cm.
