Digital indication for selectable impedance circuit |
摘要 |
A digital indication for a selectable impedance circuit consisting of a plurality of serially connected impedances and a selector which is connectable to a common junction of any of them is provided by connecting an electric signal source to the end terminals of the circuit to develop a signal between the selector and at least one of the end terminals which is compared with the output of a digital/analog converter, the converter being connected to the output of a digital counter which continues to receive clock pulses until disabled from doing so by a comparison difference within a predetermined tolerance.
