Metaplectomorphism

Posted in Uncategorized by admin on the April 29th, 2008

In mathematics and signal processing, a metaplectomorphism is a transformation by way of an operator from a metaplectic group of operators.

Examples of metaplectomorphisms, in time-frequency, include:

in time;

  • translation in frequency;
  • dilation in time (which, by the way, also results in contraction in frequency);
  • chirping (introduction of a time-varying frequency-shift);
  • dispersion (introduction of a frequency-varying time-shift).
