BER test method uses real data
Data-dependent jitter is further broken down into DCD (duty cycle distortion) and ISI (inter-symbol interference). These last two categories are dependent on the data pattern. Each form of jitter is found in a real system … Jitter injection is done …

Make Sense of Nonlinear Distortion Part 1: Viewing distortion as a modulation
Often, system specifications such as Noise Power Ratio (NPR) and Adjacent Channel Interference (ACI) cannot be flowed down to suppliers who characterize their components with simple two-tone intermodulation distortion (IMD) and 1-dB compression …

Sending wireless signals over wired fiber
CD and PMD lead to periodic power fading, while fiber Kerr effects may induce different signal degradations (self-phase and cross-phase modulation, for example), and RF nonlinearity produces serious third-order intermodulation distortions (IMD3).

AM NRSC Measurements
The potential for the generation of intermodulation products should also be considered when making NRSC measurements. The presence of another AM station in proximity, or combined into the same antenna system makes this issue a very real possibility.

Getting the best out of your precision design with Zero-Drift amplifiers, Part 2
Because the inputs are switched, it produces small transients at the chopping frequency that can mix with the input signal frequency and result in intermodulation distortion detectable at the op amp's output. To address this artifact of self-correcting …
