KARJALAINEN1996 - Non-linear adapation network

Usage

[slow,fast]=karjalainen1996(insig,fs)

[slow,fast]=karjalainen1996(insig,fs) computes the non-linear adaptation network from Karjalainen et al. (1996) on the input signal insig sampled with a sampling frequency of fs Hz.

  • XXX What are the assumptions on the input? The example below generates NaN's
  • XXX What is slow and fast? In which units are they defined?
  • XXX Which level convention is used ?
  • XXX Bibtex entry for the correct paper to cite.

Examples:

The following show the adapation to a simple test signal:

[insig,fs] = greasy;
[slow,fast]=karjalainen1996(insig,fs);

subplot(1,2,1);
plot(slow);

subplot(1,2,2);
plot(fast);
