Electrical engineers in Fort Lee design digital and analogue circuits similar to the ones on the dashboard of an automobile, and the control circuitry of the Space Shuttle. They also write programs to simulate the operation of these circuits on a computer. Another specialty is the hardware and microcode design of state-of-the-art microprocessors. They deal with the study and application of electricity, electronics, electromagnetism; they also cover a range of subtopics like power, control systems, signal processing and telecommunications. They are usually concerned with using electricity to transmit energy and deal with problems associated with large-scale electrical systems such as power transmission and motor control.
