Compensation for nonlinear distortion in the isolated transmission process of photocoupler
Hui She · Journal of Changchun Institute of Technology · 2001
Owing to the volt-ampere characteristic of light-emitting diode and phototransistor in the photocoupler, there is a nonlinear distortion in its isolated transmission process. In this paper, the author develops a simple compensating circuit to eliminate the nonlinear distortion, and introduces its working principle.
