There are instances when we want to add a collection of numbers together. Assume you want to use 1-bit full adders to add the four 4-bit numbers A, B, E, and F. The illustration depicts one potential structure. Suppose that inverters do not cause delays and that the time delay via one gate is T. Determine the time required to add four 4-bit numbers while utilizing the following organizations:

A) Gates with an unrestricted number of input signals

B) Gates with only 2 input signal
