In computer, communications, and data processing systems, a programming language that (a) is less machine-oriented than a machine language, (b) is not so machine-independent as a common language, such as Ada®, COBOL, or Fortran, (c) contains macros that are less powerful than common-language macros, and (d) usually is the object language of a root compiler. Examples of intermediate-level languages include… (Read More →)

Synonym multimode distortion.

Incorrect synonym for multimode distortion.

Synonym multimode distortion.

The production, in a nonlinear element of a system, of frequencies corresponding to the sum and difference frequencies of the fundamentals and harmonics thereof that are transmitted through the element.

Nonlinear distortion characterized by the appearance, in the output of a device, of frequencies that are linear combinations of the fundamental frequencies and all harmonics present in the input signals.
Note: Harmonic components themselves are not usually considered to characterize intermodulation distortion. When the harmonics are included as part of the distortion, a statement to that effect should be made.

In a transmission path or device, noise, generated during modulation and demodulation, that results from nonlinear characteristics in the path or device.

In the output of a nonlinear system, a frequency produced by intermodulation of harmonics of the frequencies present in the input signal.

In a start-stop teletypewriter receiving mechanism, bias generated locally by the mechanism, and which has the same effect on the operating margin as bias external to the receiver, i.e., applied bias.
Note: Internal bias may be a marking bias or a spacing bias.
