Computer Use: As part of the homework assignments, students are required to run the circuit simulation program PSpice to compare computer simulation with analysis and measurements of implemented circuits.
- Introduction to the laboratory and the PSpice and Circuit
Simulation (1 week): This is an introduction to laboratory procedures
and to PSpice and circuit simulations.
- Circuit Response to Sinusoidal Excitation (1 week): The goal of this project is to acquaint students with the laboratory equipment and to investigate the response of a simple circuit to sinusoidal excitation.
- Passive Filters (2 weeks): The goal of this project is to investigate the frequency-domain characteristics of several passive circuits and to use PSpice to simulate the circuits.
- Operational Amplifiers and Active Filters (2 weeks): The goal of this project is to investigate various common circuits involving operational amplifiers. Students derive the transfer functions of the circuits and compare the derived functions for the ideal and non-ideal cases. They use PSpice to simulate the circuits. They also build the circuits, measure their frequency responses and compare them with the simulation results.
- Noise Reduction System (4 weeks): This project involves the design of a noise reduction system that meets given specifications. The design is comprised of a preemphasis filter and a deemphasis filter. Students simulate the designed circuit using PSpice and implement it. As part of the submitted report, they perform a cost analysis of the designed circuit.
Engineering Design Statement:
In lecture students are introduced to the iterative nature of engineering design. Examples are treated in which students begin with the defining of specifications, proceed to the proposing of creative solutions, analyze and evaluate those solutions against the specifications, and iterate as necessary to refine the solution to a workable, practical, cost-effective, and manufacturable result.
In homework, the students are given an opportunity to design simple circuits to meet certain specifications.
In the laboratory students carry out four organized laboratories aimed at learning the use of the equipment and some basic circuit designs. They carry out one major project in the design of noise reduction circuit. Students must define the specifications of the circuit and must carry out iterative design to refine the circuit to meet the specifications.
