2. ### How To Generate a Random Process ??

Any one help me how to generate a Random Process, with using any MATLAB functions. I want to know that what logic behind it if I want to generate 1000 points Random Numbers, Pdf is also given with mean and Variance. But question is same How to generate the random numbers ??
3. ### Reading a 3-D image in Matlab

Re: reading a image I believe all the Imags stored in the computer memory are 2d not 3d. but their effect is a 3d. it may be in jpeg or tif
4. ### what is "one sided exponential" sequence?

Which is defined only on one side ie. right sided or left sided
5. ### Wireless communication using MATLAB

You and do digital Modulation in this regard, its easy and reliable
6. ### Solution manual for Signals and System

Re: manual solution Please go on www.gigapedia.org and get the solution
7. ### Number of samples required for FFT

You need to take samples in the frequency domain according to the nyquist critrain and do sampling the frequency axis. It will be the fft
8. ### How to change from s-parameter model to time domain

Just take inverse Laplace transform. In this way your Laplace domain will be converted into Time domain.
9. ### Need info about star tracking by image processing

Re: star tracking I think it can be done through the application of Radars
10. ### similarity of Wavelet and fourier transform

Both give you frequency information. But disadvantage of the fourier transform that it losses the time or spatial information. but Wavelet transform perserve the spatial information along with the frequency information

One way to jam a signal is, you must know the frequency of the signal to be jammed. Than generate a noisy signal of that frequency and send it on air. Your signal will be jammed easily.
12. ### How to use pilot symbols for imperfect channel estimate in Matlab

Re: pilot symbols You can easily send a bit stream from the transmitter which is already known to the receiver. Than just estimate the channl by using any adaptive filter. Winear Filter, LMS Filter and RLS Filter can be used. Make sure the bit stream of your pilot signal is already known to...
13. ### Any good reference on communication system simulation?

See MATLAB help

15. ### How to choose a DSP to use with an Inertial and MFL system?

Re: How to choose a DSP Please send your spacification, what si your requirement and what you want to do, how fast you need to process your data. than i suggest you which DSP you may use for your particular task
16. ### how to draw a line in either binary or double image??

Its very very simple, read the image by >> imread (). provided your image is in work. Than make a mask of same size as your image of all zeros (White). Now make a line in that white mask. eg >> image_name(10,20:30) = 1 ; Line will be of black color and your mask is of white color. Simply add...
17. ### What component is that ? ( 89C72 )

I think 89c72 is a Microcontroller
18. ### Phase response of of second degree differentiator

You are doing right. But if your phase difference is not equal to pi. Than plesae cascade your system with a system having magnitude responce equal to 1 but phase compansate in such a way that you got a phase difference equal to pi. All Pass System do that Easily

20. ### how to calculate perimeter in matlab,is ther any direct func

perimeter matlab You can Extrac the features by corrdinates. ie 1st estimate the coordinate location of your feature, you want to extract. Than make a window of all ones inside and zero outside. Finally do filtering in Spatial Domain.
