Explain the concept of rise time, fall time, propagation delay.

Question

Accepted Answer

Rise time, fall time, and propagation delay are important concepts in signal processing.

Rise time is the time taken by a signal to rise from 10% to 90% of its maximum value.
Fall time is the time taken by a signal to fall from 90% to 10% of its maximum value.
Propagation delay is the time taken by a signal to travel from the input to the output of a system.
Propagation delay is affected by the length of the transmission line, the speed of the signal, and the characteristics of the medium through which the signal is transmitted.
Rise time and fall time are important in digital circuits as they affect the switching speed of the circuit.
Propagation delay is important in communication systems as it affects the time taken for a signal to reach its destination.
In high-speed communication systems, minimizing propagation delay is critical to ensure reliable and fast data transmission.
