Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation but without the fixed-point access to the multi-rate filter design tool.
[psi gopt] = dfdesign_w_lmi(phi, w, d, n);
DFDESIGN_W_LMI computes the H-infinity optimal inverse FIR filter of phi(z).
The resulting filter minimizes the H-infinity norm of the error system
E_w(z) = [z^(-d) -...
his simulation shown the system identification of an FIR and also the actual and estimated coefficients
MISO_FIRWIENER(N, X, Y) computes the optimal FIR Wiener filter of order N, given any number of (stationary) random input signals as the columns of matrix X, and one output signal in column vector Y.
Requires BLOCK_LEVISON.M, also on the...
Divides an audio signal into bass and treble using FIR filters. The effect of changing the crossover frequency can be selected using the Texas Instruments TMS320C5510 DSK.
May also be applied to other devices in the C5000 family.
In this study, windowing-based Finite Impulse Response (FIR) filter design method is implemented for four regular filters ( Low Pass, Band Pass, Band Stop and High Pass). Detailed steps are described. The related codes are uploaded to the website...
2-D zero phase digital FIR filter using Hamming Window

This module integrates the CM-CIC p@iement Credit Card payment service to Ubercart.
CM-CIC p@iement is used by the following French banks:
* CrdoTedit Mutuel
* Groupe CIC
Add, move and delete points to form a desired spectral curve.
The result can be saved to workspace as linear or minimum phase FIR.
The library includes compiled FIR filters, redundant and non redundant wavelet transform with dynamically sized channels, with applications to denoising and differentiation.
A complete application written in C and assembly language to show how changing the sampling rate can be used to improve the sharpness of cut-offs of FIR filters. Shows effects of anti-aliasing and anti-imaging filters. Frequency response curves...
This demonstration shows the single steps of nearest neighbour, hungarian method (munkres algorithm) for assignment problem, branch and bound for symetric cost matrices. The tree of the branch and bound algorithm is shown and the user can select...
Java library offering theory of sets/set theory functionality (complement, intersection, symetric difference, union, cartesian product and powerset). There's also an ant task/ant tasks included that provides the library's functionality

After the run of the "MyEqualizer.m" file a graphical user interface appear. By pressing the "Load" we can load audio signal (type .wmv). After we can model the frequency behavior of the FIR filter that is used to filter that...
LMS filters in an adaptive filter architecture is a time honored means for identifying an unknown filter. By running the example code provided you can demonstrate one process to identify an unknown FIR filter.

Functions accompanying MATLAB News & Notes article "Fixed-point Signal Processing: Getting Started" by Darel A. Linebarger and Thomas A. Bryan, 2004. The functions include an FIR filter in M that can be run in fixed-point and...
- Filter can be FIR or IIR.
- Filter type can be lowpass, highpass, bandpass, or bandstop.
- Direct methods or optimization ones can be used during the design procedure.
