Design and Analysis of IIR Notch Filter using LabVIEW

This paper presents the implementation of IIR notch filter using signal processing tool kit of LabVIEW software. User interface is designed using LabVIEW to obtain the simulation results of digital IIR notch filtering technique. Simulation results are presented in terms of magnitude squared value of notch frequency for different nature of noise signals. The results shows that the designed notch filter gives best performance by extracting notch peaks from different sources of noisy signals.
