Abstract: 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; the duration of each time segment is set at a respective desired value; the time segments are scanned in an orderly manner as a function of a clock signal 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; the memory is addressed as a function of said relative time and of a ratio between the number of the samples and the desired duration of the time segment in order to read at least part of the samples of the time segment; and a digital-to-analog conversion of the samples read from the memory is carried out.
