IMPLEMENTING DIGITAL POTENTIOMETER IN IMPEDANCE MEASUREMENTS

This paper is about the importance of digital potentiometers and the possibility of implementing them in digital impedance measurements. Here we show the possibility of full digitizing of an analog bridge fated to impedance measuring. It is possible due to existence of digital potentiometers and their usage in measurement scheme. Due to digipot we can command and control an ordinary bridge. In this way we can use both the advantages of simple bridge for impedance measurement and of digital potentiometer.
