Conversion device of the frequency of a signal into a binary number, called the converter frequency - binary

摘要

P the present invention is of the electronics domain and it relates to a device for conversion of the frequency of a signal into a binary number. / p & & p & a converter of the invention is intended for the conversion rapid and precise an input signal whose frequency varies as a function of an entry measurement, in a number in the form of binary information by parallel, treatable by computer, 1984; the incoming signal to be applied to the converter 13 is in accordance with 12a and 13a of a wave train square provided with an edge, a measurement is performed during an interval of time which does not need to be synchronized with the input signal and which is independent of its frequency, having a fixed time interval which is a multiple predetermined of a unit of time; in this range the following factors are measurements in a portion of a train of waves lying between the start and end of the interval: number of unit box of time between the starting point and the edge of the first wave complete of the portion, the number of waves comprehensive located in the portion, the number of unit box of time between the latter appears in the front portion and the point of end, the measurements are applied to the computer, 1984, 10, which translates the frequency of the incoming signal in terms of the binary from an equation linking the frequency for these factors, in addition, the parameters calculated by the computer 10 are either reconverted into analog values in a converter 16, is read in non-limitative manner on a display 15. / p & & p & application to the operations of control and processing. / p
