### ABET Category

Engineering Science: 95%
Engineering Design: 5%

### Course Goals

ECE 210 is a required 4-hour course for both electrical engineering and computer engineering majors. The goals are to provide a solid foundation in analog signal processing that will serve as a strong base for further study in digital signal processing, communications, remote sensing, control, and electronics. Topics include circuit analysis, continuous- time linear system theory, Laplace and Fourier transforms, AM radio, and basic analog filter design. ECE 211 is the first half of ECE 210 and is taught as a service course for students outside electrical and computer engineering.

### Instructional Objectives

A. At the time of Exam 1 (after 14 lectures), students should be able to:

• Calculate node voltages and branch currents in linear circuits containing resistors, independent and dependent sources, and operational amplifiers. (1)
• Design simple op amp circuits. (2)
• Sketch voltage and current waveforms (given one, sketch the other) for capacitors and inductors. (1)
• Design simple op amp integrators and differentiators. (2)
• Solve first- and second-order differential equations with constant inputs. (1)
• Manipulate complex numbers and demonstrate an understanding of their meaning. (1)

B. At the time of Exam 2 (after 28 lectures), students should be able to do all of the items under A., plus:

• Understand phasor representation of co-sinusoidal signals and use the method for solving linear differential equations with co-sinusoid inputs. (1)
• Apply the phasor concept to solve circuits for the sinusoidal steady-state response. (1)
• Understand the distinction between instantaneous and average power and use the concept of maximum power transfer. (1, 2)
• Derive and sketch the frequency response of a linear circuit or system. (1)
• Calculate the response of dissipative linear systems to multi-frequency inputs (1)
• Calculate the Fourier series of a periodic signal. (1)
• Apply the Fourier series concept to calculate the output of a system due to a periodic input. (1)
