Satellite Communication A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.	Digital Electronics Digital electronics or digital circuits are electronics that operate on digital signals. Its all work done by 0's and 1's	Instrumentatio Engneering Instrumentation is defined as the art and science of measurement and control of the process variables(PID) within a production or manufacturing area.	Control Processing Control Processing done by the PID action in Inustries	Signal Processing Signal processing concerns the analysis, synthesis, and modification of signals, which are broadly defined as functions conveying, "information about the behavior or attributes of some phenomenon", such as sound, images, and biological measurements.
Telecommunication Engg Telecommunications engineering deals with the transmission of information across a channel such as a co-axial cable, optical fiber or free space.	ECE & CSE controlled robotics has required training humans to “think” in a prescribed way that computers can recognize.	Instrumentation engineering Instrumentation engineering deals with the design of devices to measure physical quantities such as pressure, flow, level and temperature. These devices are known as instrumentation.	VLSI design engineering VLSI design engineering VLSI stands for very large scale integration. It deals with fabrication of ICs and various electronic components.
