Abstract :
This paper presents an automatic measurement method based on the classic Schering bridge applying analog-to-digital (ADC) and digital-to-analog (DAC) converters, integrated circuitry and a personal computer. Two versions for the electric circuit are analysed. Theoretical models were developed in order to explain the experimental results of the circuits. Simulation results and experimental data are presented
