28 Signal Processing Toolbox 5.1 Release Notes
28-4
The general window function is an alternate way to specify any Signal
Processing Toolbox window.
The rectangular (
boxcar) window function has been renamed rectwin. For
compatibility,
boxcar will continue to work in this release.
bitrevorder
The new bitrevorder function returns input data in bit-reversed order.
downsample/upsample
The new downsample and upsample functions decrease and increase the
sampling rate of a signal, respectively.
filternorm
The new filternorm function computes the 2-norm or inf-norm of a digital
filter.
goertzel
The new goertzel function implements the Goertzel algorithm, which is an
alternate method of computing the DFT.
New Signal Demo
A new demo, Vector Transition Processing Using Spectral Windows, has been
added. This demo is interactive and demonstrates how to smooth the transition
between two vectors by using various spectral windows.
