delay line
Definition
Noun: A delay line is a circuit designed to introduce a calculated, precise delay into the transmission of an electrical signal. It temporarily stores a signal for a specific amount of time before allowing it to pass through.
Usage
A delay line is used in electronics and signal processing to manage the timing of signals. It is a technical term describing a specific component or system. - The audio processor uses a delay line to synchronize the sound from the different speakers. - In radar systems, a delay line is crucial for accurately calculating distances.
Advanced Usage
- Acoustic delay line: An early type that used a medium like mercury or a wire to physically slow down a signal, converting it to a sound wave and back.
- Early computers sometimes employed acoustic delay lines as memory devices.
- Digital delay line: A modern implementation that stores digital samples in memory to create the delay.
- The guitar pedal creates its echo effect using a sophisticated digital delay line.
Variants and Related Words
- Delay (verb/noun): To make something late or slower; the period of time by which something is late.
- The flight was delayed by bad weather.
- Transmission line (noun): A specialized cable or structure designed to carry electromagnetic waves with minimal loss, distinct from a delay line which is specifically for creating a time lag.
Synonyms
- Signal delayer: A descriptive synonym emphasizing the function.
- Time delay unit: A term highlighting the purpose of creating a temporal offset.
Related Technical Phrases
- To introduce a delay: The primary function of a delay line.
- The circuit is designed to introduce a delay of exactly 10 microseconds.
- Propagation delay: The inherent time delay a signal experiences traveling through any medium or circuit, which a delay line intentionally controls and utilizes.
Noun
-
a circuit designed to introduce a calculated delay into the transmission of a signal
