| DSP First Toolbox Additions & Updates |
The Latest GUI Files:
DSP-First M-Files:
Original ZIP file
containing all the DSP-First M-files as
distributed with the textbook (Nov-1997).
Some of these are
updated with the M-files given below.
Miscellaneous M-File Updates:
ZIP file
containing all the M-files in the table below (22-Jan-2002)
Put all these M-files into the dspfirst directory which should
be on the MATLAB path.
| NOTE: The files in this table should be transfered as ASCII files or the line terminators may be incorrect for your platform. |

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 | 10-Oct-01 | New version of this DSP-First toolbox function This version will not fail when the xx input is a matrix; instead, it will filter down each column of the matrix. Previous update for a bug fix was 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." |
| musicgui.m | 31-Aug-01 | Main GUI file for Music Lab (Ch. 9) updated for v6.x of MATLAB. Install into dspfirst/musiclab/musicgui.m |
| plotspec.m | 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 | 02-Dec-01 | New version of this DSP-First toolbox function Now accepts complex inputs, for which it produces negative frequencies in the spectrogram. Removed the dependence on the "hanning.m" window function (29-Jan-99) |
| striplot.m | 24-May-01 | New version of this DSP-First toolbox function Fixed line color to work in version 6 of MATLAB |
| ucplot.m | 24-May-01 | New version of this DSP-First toolbox function Fixed line color to work in version 6 of MATLAB |
| zcat.m | 24-May-01 | New version of this DSP-First toolbox function Fixed line color to work in version 6 of MATLAB |
| zcoords.m | 24-May-01 | New version of this DSP-First toolbox function Fixed line color to work in version 6 of MATLAB |
| zvect.m | 22-Jan-02 | Updated comments (Jan-02) New version of this DSP-First toolbox function Fixed line color to work in version 6 of MATLAB |
| zzplane.m | 27-Oct-98 | Substitute for MATLAB function called zplane.m Plots root locations in the complex plane |
