A method for digital synthesis of a waveform, wherein: samples of a reference waveform that is divided into a plurality of contiguous time segments are stored in a digital memory (2); the duration of each time segment is set at a respective desired value (Tsd); the time segments are scanned in an orderly manner as a function of a clock signal (CK) so as to select one time segment at a time; for the time segment selected, a relative time that has elapsed from the start of the time segment is calculated as a function of the clock signal (CK); the memory (2) is addressed as a function of said relative time and of a ratio between the number of the samples (N) and the desired duration (Tsd) of the time segment in order to read at least part of the samples (SD) of the time segment; and a digital-to-analog conversion of the samples (SD) read from the memory (2) is carried out. |
