Conversion circuit for converting a received serial analogue signal into the bit stream of a digital signal for further processing

摘要

The converter mounting (12) has an adjustable trigger level (20), which is updated for each impulse of its amplitude sequenced in analog signals (13,13'). A microprocessor (21) is provided for reading the analog signals for detecting the maximum and minimum amplitudes and for corresponded controlling of the digital potentiometer (22) for moving forwardly the potential of the trigger level.
