Abstract
The parallel cascade identification of nonlinear systems is used for the rapid recognition of dual tone multi-frequency (DTMF) signals, i.e. the `dual tones´ used to encode the digits on a telephone keypad. The authors demonstrate that parallel cascades can correctly identify DTMF signals with half or less than half of the input data required by current methods
