Transmission delay

Under the term is understood in electrical engineering, the difference in time between the occurrence of a signal in a ( causal ) system and the exit. The concept of the system here is very broad.

An example is the so-called gate delay time, ie the time that elapses in the processing of information in a logic gate. This can be measured using ring oscillators. The gate delay time determines the maximum frequency of the clock signal in computer systems. Specific methods for the determination of travel times in networks provides the so-called run-time tolerance calculation.

The term of free-flying electrons determines the frequency at run-time oscillators such as magnetron and klystron.

When high-performance radar, the magnetron is operated with very short, but powerful pulses. Their length is defined by the signal propagation time in a coaxial cable.

One area that deals significantly with the duration of electrical signals and their characteristics, is the time-domain reflectometry.
