Signal to noise ratio is selected as an objective measure in order to know the efficiency of the notch filter. All the necessary signals are generated using simulations on SCILAB.
SCILAB SIGNAL SOFTWARE
Hence, a second order IIR digital notch filter is designed using SCILAB which is an open source software tool to remove the interference and to present a noise free signal for the further processing by digital systems and applications. Power-line interference of 50Hz effects the accurate representation of signals as most of the signals are susceptible to the most popular 50hz noise due to the use of electronic systems. The removal of power-line interference from the signals of interest is a very important application of the notch filter.
