Increasing Order of Digital Filters of the Same Type in Robotic Systems

Abstract

Considering the issues of the filter order in a signal processing channel with sensors, through the serial link of the same type filters with low order. New approach to define cutoff frequency of such link was obtained. This solution allows quickly change the order and bandwidth of bandpass filters in robotic mobile platforms with limited computing resources. Proposed using a preliminary calculation of such frequencies, depending on the number of serial links of the same type of filters. This allows quickly rebuild the sensor signal processing channel.
