distorsjonsparametre

Distorsjonsparametre, also known as distortion parameters, are a set of metrics used to quantify the amount of distortion present in a signal, particularly in audio systems. These parameters are crucial for evaluating the quality of audio reproduction and ensuring that the original signal is accurately represented. The most common distortion parameters include:

Total Harmonic Distortion (THD): This measures the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. It provides an overall measure of the distortion present in a signal.

Total Harmonic Distortion plus Noise (THD+N): This parameter includes both harmonic distortion and noise in its measurement. It gives a more comprehensive view of the signal quality, as it accounts for all types of unwanted components.

Signal-to-Noise Ratio (SNR): SNR measures the ratio of the desired signal power to the noise power. It is a key indicator of the signal quality and the effectiveness of the system in minimizing background noise.

Intermodulation Distortion (IMD): IMD occurs when two or more signals mix and produce additional frequencies. IMD is particularly relevant in systems where multiple signals are present, such as in radio communications.

Distortion parameters are essential for engineers and audio professionals to assess the performance of audio equipment, such as amplifiers, speakers, and digital-to-analog converters. By monitoring these parameters, they can identify and mitigate sources of distortion, ensuring that the audio signal remains true to the original source.
