Propagation Delay Question & Answers

October 14, 2022 By WatElectronics

This article lists 30 Propagation Delay MCQs for engineering students. All the Propagation Delay Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, or interviews, or professionals who would like to brush up on the fundamentals of Propagation Delay.

Propagation delays must be focussed on by electrical engineers when creating ICs. Modern integrated circuits built have gates in billions and the speed of operation is incredible. If a delay of propagation in IC is inconsistent it causes race conditions as well as errors in data on the chip.

Propagation delays are considered an important aspect of designing high-speed circuits. It also limits the speed of processing at which the processor runs. It is also defined as the time acquired by components individually known as Logic gates; time taken for signals to be moved from a certain point to another one and in such situations, it is also referred to as Gate delay.

Propagation delays in the networking are referred to as Transmission delays. Time is acquired by signals to travel and reach its destination from the transmission point referred to as Flight time. The speed of the signal and the overall traveling distance are the main factors that form the overall delay of propagation.

Propagation delays are also dependent upon the type of logic families used. It can be either TTL (Transistor-transistor logic) or CMOS (Complementary Metal-oxide Semiconductor). These delays are measurable in picoseconds or nanoseconds.
