What Is a Delay Line?
A delay line is a device designed to intentionally postpone the transmission of an electrical or optical signal by a specific duration.
There are two main types of delay lines: analog and digital. Analog delay lines utilize components like capacitors and resistors to delay signals, commonly applied in audio signal processing. Conversely, digital delay lines employ digital components such as registers and memory, primarily used in processing data signals.
Delay lines find various applications, including echo generation, signal filtering, and timing adjustment. Echo generation is prevalent in music and communication systems, while signal filtering is essential for noise reduction and spectrum analysis.
