Laboratory 6 of 12 for the Texas Instruments TMS320C5416 DSK.
A self-teach application or college laboratory to allow the student to find out by practical experiment the answer to the following question:
An Infinite Impulse Response (IIR) filter can be used to implement low pass and high pass Butterworth filters, which behave in the same way as analogue (resistor-capacitor) filters. What order of filter (1st order to 6th order) is required to give acceptable cut-offs for audio work?
IIR filters from 1st order to 6th order can be selected and the effect heard.
Frequency response curves generated from supplied MATLAB source files and also in a Word document.
The application could be modified for the TMS320C5402 DSK, although this has less user switches (2 vs. 4 of 'C5416).
