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.

2020年4月7日 · 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 signals but will also contain the sum and difference …

2021年5月2日 · Intermodulation products are unwanted signals. They leak into other channels and creates distortion. As we discussed, not all the components cause problems, and most of them can be ignored and filtered out as the amplitude of harmonics decreases as the order increases in a non-linear system.

2012年6月29日 · IP3 is a well-known parameter that gauges linearity in radio frequency (RF) functions and components. This tutorial will use basic math and graphics to explain how IP3 is generated and how its values are linked to essential quantities, such as the input and output powers of a device.

ntermodulation (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.

2016年9月7日 · Understanding Intermodulation Distortion The harmonic distortion that nonlinear processing adds to single tones is widely known and understood. But apart from that, nonlinear processing adds another kind of artifact when two or more …

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 merit for these specifications and allow distortion products to be computed for various signal amplitudes.

The output will instead be distorted—a phenomenon known as Intermodulation Distortion. Q: Good heavens! This sounds terrible. What exactly is. and what will it do to our signal output?!? We have created a harmonic of the input signal!

Inter-modulation is the descriptive title for the event when two or more simultaneous signals do interact, to create others. The signals created are always products of the difference or sum of the two or more interacting signals, and most are not harmonics.

Intermodulation distortion, as the name implies, is the collection of unwanted respons-es of a circuit or component to a combination of signals. These unwanted responses are cre-ated, as the name implies, by the modulation of each signal by the others due to non-linear-ities in the circuit.
