Abstract

A signal digitizer for digitizing a continuous time varying input signal has a positive peak detector coupled to the input signal for storing the most positive peak value of the input signal and a negative peak detector coupled to the input signal for storing the most negative peak value of the input signal. Divider means are coupled to the outputs of the positive and negative peak detectors for producing a threshold voltage representative of a voltage between the outputs of the positive and negative peak detectors. A comparator has its inputs coupled to the threshold voltage and the input signal for producing a binary output signal in response to the relative values of its inputs. Limiter means are coupled to the outputs of the peak detectors for maintaining a maximum voltage potential between the peak detectors. Separator means are coupled to the outputs of the peak detectors for maintaining a minimum potential between the peak detectors regardless of the amplitude of the input signal.
