ABSTRACT:
An analog-to-digital converter is described in which a sequence of samples of an analog signal is converted into a sequence of binary numbers which appear at the output terminals of a composite counter comprising a first counter and a second counter. The first and second counters are gated in sequence by gating waveforms to provide for each sample the count corresponding to the logarithm of the sample. The gating waveforms are derived from a charge and discharge cycle of a capacitor to which the sample is supplied. Selected times in the charging and discharging portions of the cycle are utilized for deriving the gating waveforms.
