Abstract
Analog to digital conversion characterized in that the square wave (z(t)) obtained as a result of modulation in an asynchronous Sigma-Delta modulator (ASDM) is subjected to conversion by counting the periods (T) of the reference clock (RG) during subsequent pulses of the square wave by means of the counting module (CTM), and then each word obtained representing the number of periods of the reference clock counted during each given pulse of the square wave is recorded and stored in the intermediate buffer (TBUF). The duration of the serial transmission of the digital word obtained as a result of counting the periods of the reference clock during previous pulse of the square wave is simultaneously controlled by the control module (CM), and as soon as this transmission is completed, the content of the intermediate buffer (TBUF) is transferred to the transmitting buffer (TDR) of the apparatus.
