SIGNAL SYNTHESISER WITH DIRECT DIGITAL SYNTHESIS HAVING A GENERATOR OF VARIABLE AMPLITUDE INCREMENTS

摘要

The invention relates to a signal synthesiser (100), which includes: a generator (102) of variable amplitude increments, for generating an amplitude increment signal (Aa) having a variable value; an amplitude accumulator (104) for cyclically incrementing the value of a digital amplitude signal (An) of the amplitude increment signal (Aa); and a digital-to-analog converter (106),for obtaining the output signal (S, S') by converting the digital amplitude signal (An) into an analog signal.
