distortion measurement

Distortion measurement evaluates how much an audio or electronic signal deviates from its original form as it passes through a device. It quantifies unwanted changes or noise added during processing, ensuring the output remains true to the original sound or signal. Common types include harmonic distortion (undesired extra tones) and intermodulation distortion (unwanted combinations of frequencies). Accurate measurement helps engineers improve equipment quality, ensuring clear, accurate sound reproduction or signal transmission.
