Patent ID: 6958724

Claim:
A method of converting an analog actual signal to a digital desired signal using a circuit that includes a comparator having first and second input ports and one output port and a digital-to-analog converter, said method comprising: feeding the analog actual signal to said second input port of the comparator; feeding an analog output signal of the digital-to-analog converter to said first input port of the comparator; feeding the digital desired signal as a digital input signal to the digital-to-analog converter; and adapting the digital input signal fed to the digital-to-analog converter as a function of an output signal of the comparator, in a definable number of iterative steps, between definable lower and upper thresholds according to a balancing process, the digital input signal in each case fed to the digital-to-analog converter corresponding to the digital desired signal to which the analog actual signal is converted; wherein, the analog actual signal comprises a burst that includes a definable number of pulses; said step of feeding said analog actual signal comprises feeding a preselected pulse, from a preselected position within the burst, to the second input port of the comparator; and based on the preselected pulse, in the comparator, a signal value is processed which corresponds to a pulse center thereof.
