The converter has a sine signal angularly modulated by a noise signal, alternatively it can be modulated by a pseudo-random signal. The dither signal, superimposed at the input, is separated by a digital filter. The dither signal is generated by an angular modulation of a sine signal, or pseudo-random signal, ie. a noise signal generated by a digital algorithm in a pseudo-random generated, FM, PM, FSK, PSK can be used for the angular modulation.
