hi i want to to create a small robot controlled by Bluetooth of cell phone but i wondered about how the robot can receive this signal ? what is the technique i should use in my tiny robot so i can control it ?

he says >> plotopt - plotting option (type 'R' for plotting reflectivity, 'A' for absorptivity or 'RA' for both) ... i know about m-file already !. but there's no function called (plotting option ) .so the problem is how can i use this in matlab. what is the function...

ppoonamk i know that . but what is the importance? . is this mode have something special in frequency or range or ..., ? and how ?

how can i use this in code ?

How to benefit me ? actually i don't understand why this mode is very important . and Why singled this specifically mode ?

hi in wave guide and transmission line i didn't understand what is the importance of TE11 mode ... any help !

from this site >> http://www.mysimlabs.com/matlab/auxiliary/fresnelplot.m

i am using MATLAB 2009 . and gives the error (( ? Undefined function or variable 'plotopt'.))...

error in defined expression for Fresnel equation in MATLAB (urgent please )?? hi i have code for plotting Fresnel equation but there's something i didn't understand it and gives error >>((( plotopt - plotting option (type 'R' for plotting reflectivity, % 'A' for absorptivity or 'RA'...

the same code but i change tripulse to sin >> fs = 10000; t = -1:1/fs:1; x1 = sin(t,20e-3); plot(t,x1), xlabel('Time (sec)');ylabel('Amplitude'); title('sin Aperiodic Pulse')

i don't know how i can use MATLAB to plot anti periodic fun .. the origin site give this code for triangular fun: fs = 10000; t = -1:1/fs:1; x1 = tripuls(t,20e-3); plot(t,x1), xlabel('Time (sec)');ylabel('Amplitude'); title('Triangular Aperiodic Pulse') but when i use this for sine...

1st thanks for response :) 2nd the titles that interest me : about the process to convert signal from analog to digital .. the ways to transmitted and received signal plus the block diagrams ...how i can find the noise and power .. and types of modulation and demodulation of digital ... and i...

question for experienced -- digital communication books i want name of book for digital communication useful and simple way to present contents that i can study by my self thanks in advance

:D thank you so much ..

the original problem is : convolution between 2 function ( sine wave and delta function ) but when he sketch delta function ..gives two vertical lines ..one of them at x=0 upward and the other at x=2 downward ... so how can i solve this ?! and I really appreciate your assistance :)
