Described is a signal-analysis device (1) with at least one tensioned string (E1, H2, G3, D4, A5, E6) whose oscillating length can be varied by pressing the string against at least one tie-bar, the device also having a receiver (2) and an evaluation unit (3 to 9) connected to the receiver. The aim of the invention is to provide a guitar synthesizer which provides the desired note data relatively rapidly after stimulation of the string. This is achieved by vertue of the fact that the evaluation unit (3 to 9) detects pulses or pulse groups which, following stimulation of the string (E1, H2, G3, D4, A5, E6), pass along the string past the receiver (2), the evaluation unit generating from the sequence of pulses or pulse groups a signal which represents a note.
Il est décrit un dispositif d'analyse de signaux (1) comprenant au moins une corde tendue (E1, H2, G3, D4, A5, E6), dont on peut faire varier la longueur vibrante en pressant la corde contre au moins une frette, ainsi qu'un récepteur (2) et un dispositif d'évaluation (3-9) lié au récepteur. L'invention a pour but d'obtenir un synthétiseur-guitare, capable de fournir relativement rapidement, après excitation de la corde, les informations voulues de tonalité. Ce but est atteint grâce au fait que le dispositif d'estimation (3-9) détecte des impulsions ou des groupes d'impulsions qui, après excitation des cordes (E1, H2, G3, D4, A5, E6), passent le long de la corde devant le récepteur (2), et fournit, à partir de la séquence d'impulsions ou de groupes d'impulsions, un signal représentant une note.
