FIR Filters of Variable Length for the Texas Instruments TMS320C5416 DSK

Determining how many coefficients are required for a FIR filter.

Description

Laboratory 4 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: How many coefficients are required when implementing a FIR filter for clear division between one range and another?Different filter lengths may 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).

• Required Products: Filter Design Toolbox
• MATLAB release: MATLAB 6.5 (R13)
• Other requirements: Program capable of reading Word documents, Texas Instruments TMS320C5416 DSK, a CD player and connecting cable, a signal generator is also useful in producing quantitative results. Headphones or powered computer loudspeakers also needed.
