Tad - a / d - transducer having a pulse delay circuit which, before each conversion to obtain a digital output value is initialized

摘要

In a tad - (time - analogous to that of - digital) - a / d - transducer, in the case of the delay units of a pulse delay circuit, one after another, during each of successive measuring intervals a pulse signal transmitted, wherein each delay unit a by means of an analog input signal voltage certain amount of delay, it is ensured that each new measuring interval begins as soon as the pulse delay circuit according to the preceding measuring interval in a initialized state has been reset. Initial values, which the number of of the pulse signal during a measuring interval traversed delay units describe, are directly as the analog input signal voltage level digital values describing used.
