### Course Director

### Description

Introduction to analog signal processing, with an emphasis on underlying concepts from circuit and system analysis: linear systems, review of elementary circuit analysis, differential equation models of linear circuits and systems, Laplace transform, convolution, stability, phasors, frequency response, Fourier series, Fourier transform, active filters and AM radio.

### Notes

Students may not receive credit for both ECE 211 and 210.

### Goals

### 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 Prerequisites

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

### ABET Category

Engineering Design: 10%

### 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 (1), (2), and (6) 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.
