A device for converting the setting of a potentiometer or the like, by a binary word, in particular used in a system of an agreement for a radio receiver -

摘要

P the invention relates to a device comprising a comparator for generating an output signal having a first level when the amplitude of a first input signal exceeds that of a second, and a second in the opposite case, a voltage divider with respect to be adjustable in order to generate the first signal by dividing a reference voltage, a first capacitor with a first means of a load during a first period in order to generate the second signal, the output signal changing the level during the first period, determined by the ratio. / p & & p & according to the invention, there is provided a second capacitor 59, with a second charging means 49, 57, 61 for a second period after the first, in response to the magnitude of the second input voltage at the end of the first period, in order to develop the reference voltage; and a means of use, 33, 35, 37, 39, 41, 51 which is sensitive to the output signal in order to generate a binary word. / p & & p & the invention applies in particular to the radio - transmitters. / p
