Labview-based laboratory environment for learning of filtering concepts

Abstract

Better understanding of the acquired theoretical knowledge in the field of digital signal processing, for their successful use in future engineering practice, is achieved by introducing interactive laboratory experiments in the classroom. In this paper we present realization of LabVIEW virtual interactive DSP experiments and hardware DSP laboratory experiments on the NI-ELVIS II + development platform. These experiments can be used in the DSP lab for “visualization” of filtering concepts. For the purpose of “visualization”, LabVIEW filter palette has been used for the procedure of band pass digital filter design and active band pass filter has been realized on the NI-ELVIS II+ developing platform. Theoretical characteristics of active band pass filter validated by measurements on realized hardware model.
