Simple Explanation

A test signal that sweeps through a range of frequencies over time.

Concise Technical Definition

An electronic test signal, typically a swept sine wave or burst, that changes frequency over a defined time period to assess acoustic or system responses.

Layman-Friendly Analogy

Like a siren that gradually changes pitch, letting you hear every frequency along the way.

Industry Usage Summary

Widely used in acoustic testing, calibration, and system identification to measure frequency response, impulse response, and identify resonances or distortions.

Engineering Shortcut

Chirp = frequency sweep (swept sine or burst); measures system response.

Full Technical Explanation

A chirp signal is a type of electronic test signal in which the frequency increases or decreases steadily over time. Commonly implemented as a swept sine wave or burst, chirp signals are employed in acoustics and electronics to evaluate system characteristics such as frequency response, phase, and transient behavior. They are essential in room calibration, loudspeaker testing, and impulse response measurement, providing detailed insights into system performance.
