Subfields of electrical engineering Neither digital computers nor antennas nor radar was mentioned as important subfields of electrical engineering especially in the introductory sections I have a B E E and an M S E E and I have also taught at several schools in the United States On the undergraduate level these divided the subfields of electrical engineering usually quite specifically into these subfields given here in a random order so do not read anything into the order 1 Digital electronic circuits digital computers 2 Communication systems analog digital senior level 3 Control systems analog digital 4 Basic through intermediate analog circuits all required courses of course 5 Basic and analog electronic circuits e g starting with diodes and transistors and progressing though analog op amp circuits 6 Electic power usage conversion and transmission e g generators motors transformers and big electric power systems with long range transmission 7 Basic through senior level electromagnetic theory applications
