Question

The digital logic family which has the lowest propagation delay time is?

Answer 1

It can be computed as the ratio between the link length and the propagation speed over the specific medium. Propagation delay is equal to d / s where d is the distance and s is the wave propagation speed. In wireless communication, s=c, i.e. the speed of light.

Answer 2

Answer:

TTL has the lowest propagation delay time
