Question

If several gates are arranged in series, their propagation delays are subtractive.

a) True
b) False

Answer 1

False. The statement that if several gates are arranged in series, their propagation delays are subtractive is false. When gates are arranged in series, each gate introduces a delay in the signal propagation. In a series arrangement, the delays add up, resulting in a longer total propagation delay compared to a single gate.

Step-by-step explanation:

The statement that if several gates are arranged in series, their propagation delays are subtractive is false.

When gates are arranged in series, each gate introduces a delay in the signal propagation. In a series arrangement, the delays add up, resulting in a longer total propagation delay compared to a single gate. This is because the output of each gate becomes the input to the next gate, and the signal has to propagate through each gate sequentially.

For example, if gate 1 has a delay of 5 nanoseconds and gate 2 has a delay of 3 nanoseconds, the total propagation delay for the series arrangement would be 8 nanoseconds (5 nanoseconds + 3 nanoseconds).
