Digital implementation of RC low pass filter

by Krishna Sankar on December 2, 2007

Step response of a digital RC low pass filter

Thanks to the nice article from Xilinx TechXclusives [XLNX-TECH], let us try to understand the probable digital implementation of resistor-capacitor based low pass filter. Consider a simple RC filter shown in the figure below. Assuming [...]
