    3D radiation pattern of cirular loop antenna - Matlab

    Hello I have a project to simulate radiation pattern of circular loop antenna. I have D=fn(theta,phi), and I do transform from theta,phi to x,y,z by these equations: x=D.*sin(theta).*cos(phi) y=D.*sin(theta).*sin(phi) z=D.*cos(theta) I managed to get radiation pattern in X-Y, Y-Z, X-Z planes...

    PC Based oscilloscope problems

    Hello I want to construct PC based oscilloscope. I made a simple design and these are problems that face me: 1- My adc range from 0:5 v and it doesn't read -ve values. So I thought about make a dc offset to overcome this problem. But the question now is that i want to make Variable offset. I...
