Transitional state estimation interpretation using a Kalman filter approach in the automotive industry

This paper aims to introduce a new area of usage for the Kalman filtering for evaluating the state of software generated PWM (pulse width modulation) signal. The goal was to implement a Kalman filter in a test and measurement application for the automotive industry, using real time processing and post processing techniques and provide an analysis a PWM transitional signal analysis, power factor for a light driver module.
