Listing of Communication in Scripts

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal). The package also includes two examples.

In Radars, range resolution and long range of operation are the two important aspects. Long range operation means the maximum distance over which radar can detect the targets. The radar transmit modulated pulses to take the advantages of better processing gain and resolution of these waveforms are compared to continuous wave pulse.

This example using Matlab commands to access Simulink Signal properties to easily create a batch file that can log almost any Simulink signals. This is very useful for batch testing when the parameters in the Simulink model are set in a m-file. It helps to reduce the use of Save-To-Workspace blocks.

The AudioDevice blocks that ship with Signal Processing Blockset utilize the PortAudio library to communicate with the audio hardware. Although the PortAudio library supports a range of API's designed to communicate with the audio hardware on a given platform, the following choices were made for the version of PortAudio that is built for Simulink: Windows: DirectSound Linux: OSS Mac: CoreAudio If you wish to enable communication between Simulink and your audio device using a different API, it is possible to build your own version of the PortAudio library and use it in place of the PortAudio library that ships with the Signal Processing Blockset.

This function displays the PSNR (peak signal-to-noise ratio) between two images. The answer is in decibels (dB). PSNR is very common in image processing. A sample use is in the comparison between an original image and a coded/decoded image. Typical quoted PSNR figures are in the range +25 to +35dB.

Hello, Can anyone help me debug my "Single Phase Inverter" model? I have it semi-made, i have pwm features in there, but i just can't get it to work. I need to achieve a Pure Sine Wave, at the output. And also at variable frequencies. I have a transformer attached at the output too, to achieve multiple ranges of voltage outputs.
