An Online Digital Filters and Sound Effects Laboratory Utilizing NI SPEEDY 33 and LabVIEW DSP Module

There has been an increasing use and application of the internet due to the advances in technology. At Makerere University, the internet has been used by students to remotely access and share scarce laboratory resources using the iLabs platform. This paper presents the design and implementation of an on-line laboratory that supports experimentation in Digital Filters and Sound Effects based on digital signal processing techniques. In the laboratory design, the National Instruments Signal Processing Educational Engineering Device for Youth (NI SPEEDY 33) is programmed to carry out the different processing on an applied signal at the input using the Lab VIEW DSP Module. The input is an audio signal and the output is a modified audio signal whose wave form is be displayed at the client. The online laboratory is developed using the interactive iLabs Shared Architecture that allows more student interaction with the hard ware.
