Detailed Description and Outline

  • Signals and signal processing in analog linear time-invariant (LTI) circuits and systems
  • Review of DC circuit analysis: KCL, KVL, dependent sources
  • Capacitors and inductors as circuit elements, op amps
  • Characterization and solution of LTI systems via linear, constant-coefficient differential equations
  • Complex numbers and functions of a complex variable, impedance, phasors, and sinusoidal steady-state
  • Frequency response and multi-frequency circuits, Fourier series and transforms, AM radio
  • Convolution, impulse and impulse response, sampling theorem and system stability
  • Laplace transform and transfer function, Laplace transform solution of differential equations
  • General form of solution to a differential equation, design of active filters
Computer Usage

Optional MATLAB and Python Honors Sections are offered to introduce the students to elements of scientific computing and graphics.

Lab Projects

Five bi-weekly labs introduce the students to op-amp amplifiers, mixers, and filters. Students build a superhetrodyne AM receiver in Lab 4. In Lab 5 the receiver is modified to replace its IF section with a sound-card based sampler and software radio implementation.

Topical Prerequisities
  • Calculus
  • Concurrent registration in differential equations
  • Physics-bases treatment of electricity and magnetism
  • Introductory exposure to circuit analysis

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. The course includes five laboratories to give students hands-on experience in exercising the theoretical concepts learned in class. The labs contain significant components of categories (a), (b), (c), (e), and (k) under Criterion 3, ABET Program Outcomes and Assessment. ECE 211 is the first half of ECE 210 and is taught as a service course for students outside electrical and computer engineering.
