DSP First Toolbox Additions & Updates |
The Latest GUI Files:
DSP-First M-Files:
SP-First M-Files:
A new textbook,
Signal Processing First,
has been published
in Jan-2003. The latest versions of the M-files, and other improvements,
are available with that book.
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. |

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 | 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 |
