Title (EN) DIGITAL WAVEFORM GENERATOR HAVING CONSTANT SIGNAL TO NOISE RATIO
(FR) GENERATEUR DE FORMES D"ONDES NUMERIQUES AYANT UN RAPPORT CONSTANT SIGNAUX-BRUITS
Abstract: front page image
(EN)An electronic musical instrument (Fig. 3) includes a p-bit memory (20) sequentially storing the resolution contributing bits of a sequence of n-bit samples, the n-bit sequence representing a percussive-type waveform. The p-bit memory is sequentially addressed with each stored sample being suitably scaled (26) for reestablishing the magnitudes of the corresponding n-bit samples, the scaled samples being coupled through a digital to analog converter (38) for producing an output signal representing the percussive waveform and having a uniform signal to quantizing noise ratio.
(FR)Un instrument de musique electronique (Fig. 3) comprend une memoire de p-bits (20) qui emmagasinne sequentiellement des bits de resolution d"une sequence d"echantillons de n-bits, la sequence de n-bits representant une forme d"ondes du type a percussion. La memoire de p-bits est adressee sequentiellement avec chaque echantillon emmagasine echelonne de maniere appropriee (26) pour reetablir les magnitudes des echantillons de n-bits correspondants les echantillons echelonnes etant accouples par l"intermediaire d"un convertisseur numerique-analogique (38) pour produire un signal de sortie representant la forme d"ondes de percussion et ayant un rapport uniforme signaux-bruits de quantisation.
