A high-quality interface for visualizing 1-D signals and analysis results. It can handle big files and it features a plugin-interface that allows visualization and editing of signal-related information.
Let us assume the signal model:
This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly...
A recursive implementation of the Gaussian filter. This implementation yields an infinite impulse response filter that has 6 MADDs per dimension independent of the value of sigma in the Gaussian kernel.
Recursive Gabor filtering for 1D...
This toolbox includes routines for using principal component analysis (PCA) and independent component analysis (ICA) to extract cellular signals from imaging data sets. A full description and validation of the method is provided in the paper,...
This model shows how you can model simple Buffer and UnBuffer
using just Simulink blocks.
A simple utility I''ve created to aid in building Simulink models.
You can test the correctness of the models in comparison to an ideal
using this code user can actually feel the effect of filtering on audio signals and also see how filtering varies with changing the filter used
With this Fourier Calculator a periodic signal can be analyzed and represented in figures with harmonics.
The signals can easily be produced in the model.
In this model i have used H-bridge mosfets for switching, and an inductor as a filter, R and C as a load(C=90% and R=10% which is a piezo actuator).I have used PWM generator to control the switches, in that i have used internal genration of...
These models demonstrate the usefulness of the following SimulinkdlTÂ« diagnostics:
- Solver Settings
- Connectivity: Mux used to create bus signals
This could be very useful model when used in signal processing. I have implemented this to filter the disturbances in my ADC signals in my programming and it works good.
This code provides a tool to identify a state space model from stochastic signals using a subspace approach.
The code is implemented in two steps using a nested function. The first step returns a vector of subspace singular values, from...
audioread provides a single, unified function for reading audio files in a range of different file formats, including wav, mp3, aac, flac, AIFF, etc. In most cases, access is actually provided by external binaries, but this is hidden within...
simple means of frequency domain analysis tool.Particularly used for stationary signals
Calculates the average log-spectral distance between CLEAN and NOISY signals. It has the capability of calculating this distance for a specified sub-band as well. This measure is used for evaluation of processed speech quality in comparison to the...
This program analyzes the performance of a voltage source inverter with Sinusoidal-pulse-modulated output, under different loading conditions.
The inputs are:
- The frequency of the output voltage waveform.
- The modulation...
These files just to simulate or demo M-QAM modem in case BER, channel model, signals in t and f domain.
Overal proses from bit insertion at modulator to bit estimated in demodulator. We can see the change of signal in each block diagram.
gmsk modulation of numerical data generated by a random source, the output of the modulator give two signals, only for demonstration, the first is gmsk signal and the other is gaussien frequency pulse shape
These m-files are generic implementation of distortion of signals
A signal object (an object of class "signal") is a set of data in an one dimensional array, combined with information about its sample rate, starting time and other useful infos. A number of methods makes it easy to generate and modify...
With improvements in signal processing some new models with enhanced features are made available.TVAR is on similar pattern.This model is better than conventional am-fm model in some respect as it facilates the implementation of same algo on...
