M-file |
Date | Change |
|---|---|---|
| airgnotes.m | 18-Sept-99 | Initializes vectors of note values and types for generating "Air on a G-String." |
| airgshort.m | 18-Sept-99 | Initializes vectors of note values and types for first two measures of "Air on a G-String." |
| dirich.m | 7-Oct-99 | Substitute for MATLAB function called diric.m Calculates the Dirichlet function |
| dtmfcut.m | 1-Mar-99 | Needed for DTMF Lab |
| dtmfskeletons.m | 1-Mar-99 | Needed for DTMF Lab |
| firfilt.m | 23-April-01 | New version of this DSP-First toolbox function Original version has a BUG when the filter length is 1. First argument must be shorter (fixed finally on 23-April-01) |
| freekz.m | 15-April-2001 | Substitute for MATLAB function called freqz.m Calculates the frequency response of a digital filter The comments were updated in 2001. ***CHANGED the behavior for ‘whole’, so that the frequency interval from -pi to +pi is generated instead of 0 to 2pi. |
| hamming.m | 28-Oct-98 | Just in case hamming.m is needed elsewhere |
| hanning.m | 28-Oct-98 | von Hann window might be needed in spectgr.m |
| image2bmp.m | 19-Feb-00 | Convert image to a bit map graphics file |
| j_notes.m | Feb-99 | Initializes vectors of note values and durations for generating "Jesu, Joy of Man’s Desiring." |
| mignotes.m | 23-April-99 | Initializes vectors of note values and durations for generating "Minuet in G." |
| migshort.m | 23-April-99 | Initializes vectors of note values and durations for 1st 8 measures of "Minuet in G." |
| plotspec.m | 18-Oct-98
(Update 20-Sept-00) |
Image display of the SPECTROGRAM output from spectgr.m Takes care of default settings !!!! Added "Window Length" capability |
| showspec.m | 11-Oct-98 | Substituted Hamming as in-line code Fixes existing DSP First Toolbox function |
| spectgr.m | 29-Jan-99 | New version of this DSP-First toolbox function Removes the dependence on the "hanning.m" window function |
| zzplane.m | 27-Oct-98 | Substitute for MATLAB function called zplane.m Plots root locations in the complex plane |
