Digital modulation techniques. Digital shift keying..

  • Platform: Matlab, Scripts

Returns equivalent IIR coefficients for an analog RC filter Usage: [B,A] = RC_FILTER(r, c, fs, type); R is the resistance value (in ohms) C is the capacitance value (in farrads) FS is the digital sample rate (in Hz) type is a character string defining filter type Choices are: 'high' or 'low' This function uses a pre-calculated equation for both of these circuits that only requires the resistance and capacitance value to get a true digital filter equivalent to a basic analog filter.

  • Platform: Matlab, Scripts

Digital Signal Processing: Principles and Applications examples and exercises using MATLAB Companion S.

  • Platform: Matlab, Scripts

it finds the shortest path from the given network having given no of links between given no of nodes and plots the given network as well as the modified network having shortest path in terms of cost.

  • Platform: Matlab, Scripts

Given adjacent matrix (transmat) and starting/ending node (pathS, pathE), this function finds the shortest-path (path) that connecting pathS and pathE, and returns the cost (cost): [path, cost]=dijkstra(pathS, pathE, transmat); NOTE: Except for the simple interface, the pathS and pathE can be the same node, i.

Dilates a time series input and resizes it to the orignal sample length input. If a matrix is input, dilation is done along columns. % The up/down sampling is done via resample.m, so low-pass filtering of the up/downsampling is automatically implemented.

  • Platform: Matlab, Scripts

Using Boolean Algebra technique for C6711 DSK DIP Switches to select different types of digital filters. This model works inside C6711 DSK. Please feel free to comment..

  • Platform: Matlab, Scripts

This m-fine plots the transmitted and received signal of simple DS-SS modulation.This uses BPSK modulation for data.

  • Platform: Matlab, Scripts

It will ask for input the bit stream then generate pseudorandom bit sequence, finally give output as direct sequence spread spectrum......

  • Platform: Matlab, Scripts

  • Platform: Matlab, Scripts

Comparison with fft function is also shown..

  • Platform: Matlab, Scripts

function [g] = FFTPF1D (X,binsize, f, P) Discrete Fourier Transform Low/High Pass Filter. % This is a simply implement of such a filter for a given 1-D data. X: the array of you data, each data point is a bin of signal binsize: the bin size in your data data f: the cutoff of wave length, P: 1, or 0, true or false : true, low pass, which eliminating higher than f frequence signals, false, high pass, which eliminating lower than f frequence signals.

  • Platform: Matlab, Scripts

computes the discrete walsh transform.

  • Platform: Matlab, Scripts

It is very fast and simple file to display histogram of a 3D image imhist3(I,n) n is the number of bins in the histogram imhist3(X,map) X isindexed 3D image and map is colormap map.

DphpBB3 Last Topics module (mod_dphpbb3_last_topics) shows the last topics from your phpBB 3.0.x forum. It's the excellent module for Joomla! 1.5 site with phpBB3 forum to display forum activity on the site. There is no need to integrate forum and site, forum and site may use different databases (and servers) d-deOCL everything configurable.

Embedded MATLAB block provides a way of bringing restricted subset of MATLAB into Simulink. There are couple of possibilities when moving untimed MATLAB algorithms into Simulink. This demo illustrates two such alternatives in porting a sample viterbi algorithm (written in M) into Simulink using embedded MATLAB.

In this document I show how to verify the functionality of your DSP code via processor in-the-loop (PIL) co-simulation using Simulink?s UDP (user datagram protocol) blocks. These blocks are a new addition to the R2006b release of Simulink. This example is an extension of a previous example which was based on using Texas Instrument?s RTDX (real-time data exchange) instead of UDP.
