This collection contains M-files intended for design of the Mass/Damper/Spring control system using the newly available functions from Robust Control Toolbox,version 3. Description of the system and version of the files using functions from mu-toolbox can be found in the book ?Robust Control Design with MATLAB? by Da-Wei Gu, Petko H. Petkov and Mihail M. Konstantinov, Springer-Verlag, London,...
This tutorial/demo presents the design of a sound level meter in Matlab. The Data Acquisition Toolbox is used to implement a real-time spectrum analyzer. The decibel meter is implemented in the frequency domain using Parseval's relation.
This is a simple algorithm that downloads trading data from yahoo database. It is basically a large scale application of sqq.m which was originally submitted by Michael Boldin, link at acknowledgements.
Some of the functionalities of...
Derives the transfer function for digital implementation of a first order RC low pass filter and plots the step and frequency response.
For details, refer to the post:
The script uses only one transmission symbol per frequency hop.
This package contrasts and compares the response of SAW correlators to user-specified BPSK codes based upon finger number, carrier frequency, temperature differences, frequency shifts, and substrate. Also included is a SAW filter design module and...
SpikeTrain is a GUI summarizing several functions for the analysis of electrophysiological data.
It provides multiselection of data, so a whole bunch of data can be analyzed at once.
For spike discrimination the user can...
This estimation method is based on well known paper.

caculate the dielectrics of rough surface ,especially the soil
This directory contains MATLAB functions for a simple model of GPR performance
that takes into account soil texture and water content in predicting
Real Time Analyzer uses your sound card input and analyze the frequency response.
This application works like a real spectrum analyzer. It uses the line / mic input of the sound card and is great for testing speaker response.
MATLAB script which can be used to complete a peak search on a spectrum trace extracted from an RSA6100A Real-Time Spectrum Analyzer.
- Start Frequency
- Stop Frequency
- Number of...
The Hardy Weinberg equilibrium is a fundamental law in genetic.
This function was deeply rewrited.
If a locus is biallelic the function use the exact Hardy Weinberg test (similar to Fisher exact test) analyzing all possible tables. If...
SPWM technique for Three Phase Inverter. Analysis fundamental improvement with respect to modulation index variation is done in simulation. Analysis can be done also for switching frequency variation for shifting the dominant harmonics
Compute the discrete Fourier transform at specified frequencies, not using fft.
Why one may need this?
(1) MATLAB fft function computes the amplitude of signals only (no phase).
(2) Once having the recorded time-series data,...
IMCTUNE software facilitates the design and tuning of the following types of controllers with or without model uncertainty.
?SISO and MIMO 1DF IMC controllers
?SISO and MIMO 2DF IMC controllers
?SISO and MIMO MSF IMC controllers
Multiband spectral subtraction as proposed by Kamath 2002. Uses adjusts the subtraction coefficient with the frequency as well as the SNR. note that the first 0.25sec of your signal is used to model the noise.
The demonstration of n-PSK modulation and demodulation with my own speech, with different value of n and sampling frequency and carrier, n = 2, 4, 8, 16 ,32...
A still atmosphere attenuates sound as a function of frequency, temperature, relative humidity, and propagation distance. This function uses equations published by Bass et al. to calcuate the attenuation of sound for the input parameters. The...
This program add and multiplies two signals. It also displaces, amplifies and changes the frequency of the signal.
