| File Information |
| Description |
The zipped file contains 18 m files implementing all experiments in the course EC1302 DSP Lab under Anna University Chennai, India syllabus: butterworth lowpass filter design using bilinear transformation & impulse invariant methods given relative or absolute specifications, DIT-FFT & DIF-FFT algorithms, FIR filter design using window method, sectioned or fast convolution methods (overlap-add & -save), forming a square matrix by circular-shifting of a vector (used in matrix method of convolution). Please feel free to mail me in case of any further clarification or assistance in using matlab for signal processing or in any engineering field: vsalaiselvam@yahoo.com. I am happy to share my knowledge & lecture notes as well. Thank you. |
| MATLAB release |
MATLAB 7 (R14)
|
| Other requirements |
This highly compatible with all versions of matlab from ver 4 onwards and with octave (a free matlab alternate). |
