|DSP First Toolbox Additions &
The Latest GUI Files:
containing all the DSP-First M-files
as distributed with the textbook. Some of these are updated with the files given below. (23-April-01)
Miscellaneous M-File Updates:
|NOTE: The files in this table should
be transfered as ASCII files or the line terminators may
be incorrect for your platform.
|airgnotes.m||18-Sept-99||Initializes vectors of note values
for generating "Air on a G-String."
|airgshort.m||18-Sept-99||Initializes vectors of note values
for first two measures of "Air on a G-String."
|dirich.m||7-Oct-99||Substitute for MATLAB function
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
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
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
|hanning.m||28-Oct-98||von Hann window might be needed in
|image2bmp.m||19-Feb-00||Convert image to a bit map graphics
|j_notes.m||Feb-99||Initializes vectors of note values
for generating "Jesu, Joy of Man’s Desiring."
|mignotes.m||23-April-99||Initializes vectors of note values
for generating "Minuet in G."
|migshort.m||23-April-99||Initializes vectors of note values
for 1st 8 measures of "Minuet in G."
|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
Removes the dependence on the "hanning.m"
|zzplane.m||27-Oct-98||Substitute for MATLAB function
Plots root locations in the complex plane
