I-Introduction:

The course Circuits and Systems I, taught in the Engineering Science Program at Borough of Manhattan Community College corresponds to a typical course taken by second year engineering students in the fields of Electrical, Mechanical and Chemical Engineering. The course is mostly concentrated in the analysis of DC Circuits and the time response of First and Second Order Circuits. This course had been taught for several years without any concurrent laboratory component due to a lack of funding to develop and implement a laboratory. This resulted in a separation between theory and reality, which produced lack of experimental skills and low motivation for the course, except among students intending to pursue a degree in Electrical Engineering. A NSF grant allowed us to develop a laboratory(1) that included experiments covering the majority of the contents taught in lecture(2). The experimental set-up included instruments that could be used both in stand-along as well as in PC-controlled mode. Students initially had challenging weeks learning circuit simulation software, developing proto-boarding skills, importing into and doing data processing with Matlab(3), and preparing reports. However, as the course progressed, they became more and more satisfied with their new learned skills and obtained a more solid understanding of the lecture material.

II-Contents in the laboratory manual:

The table of contents in the developed manual is shown below. Not all listed laboratory activities can be performed in a 14 weeks term, however, having extra activities is desirable for special projects and extra credit.
