Intermodulation (IM) or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies, caused by nonlinearities or time variance in a system.

Apr 7, 2020 · Intermodulation Distortion (IMD) occurs when two or more signals are used in a non-linear system. The spectrum at the output of the non-linear device will not only consist of the original …

May 28, 2025 · In this article, we’ll use a two-tone input test to examine intermodulation distortion in a memoryless, nonlinear system. We’ll also learn about the third-order intercept point (IP 3), an …

Sep 23, 2025 · Intermodulation distortion happens when two or more signals pass through a nonlinear device and generate additional, unwanted frequencies. These new frequencies, called …

IMD (intermodulation Distortion) is one of the main culprits that can make amplifiers sound 'bad'. It's heavily reliant on harmonic distortion (THD - total harmonic distortion plus noise), but not in any …

Intermodulation distortion (IMD) is a popular measure of the linearity of amplifiers, gain blocks, mixers, and other RF components. The second and third-order intercept points (IP2 and IP3) are figures of …

Jul 27, 2025 · Intermodulation Distortion, or IMD, is a phenomenon that affects RF wireless communication systems and networks in a very drastic manner. IMD is produced when two or more …

Loudspeakers and other electro-acoustical transducers generate significant intermodulation distortions in the audio band which have a significant impact on the perceived sound quality.

Oct 9, 2013 · Intermodulation distortion is an important metric of linearity for a wide range of RF and microwave components. Fundamentally, it describes the ratio (in dB) between the power of …

Jul 22, 2025 · In this article, Christian Luther from Playfair Audio takes a deep dive into what intermodulation distortion is, how it differs from harmonic distortion, and why every professional …
