| 20080284409 | Signal Recognition Method With a Low-Cost Microcontroller - The present invention relates to a signal recognition method provided that the signal is limited in time and is periodic, comprising obtaining the envelope, taking samples of the instantaneous value of its amplitude which, by means of several time parameters and their comparison with different reference matrixes, allows identifying the belonging thereof to one of said matrixes by means of the use of a low-cost microcontroller, given that the required computational power is to perform basic computation operations incorporated in the simplest microcontrollers. | 11-20-2008 |
