Object of the work is a new algorythm to detect pitch pulses position. The algorithm, based on the properties of linear prediction residual, locates the time position of the glottal pulse; it can be succesfully used as a preprocessing for pitch syncronous analisys. The special case of 200 Hz high pass filtered speech signal is used as a stress test of the algorithm.
