Modulation Technique and Density

Modulation is a technique for converting one form of information to another form. In satellite communications this is the digital conversion to analogue for transmissions over the satellite link. In the modulation process multiple digital bits can be converted in to one analogue symbol. The reverse process is called demodulation. Phase-Shift-Keying (PSK) is commonly used […]

NEMA Stepper Motors

The first part of my auto-point satellite antenna (RoboSat Project) is to get some stepper motors that can be controlled by an Arduino UNO. I decided to use stepper motors for their accuracy and are readily available being used in many 3D printers and CNC machines. The knowledge base, open source code and help available […]
