(3 units Lecture MWF 1-2 PM; 1 unit Laboratory Th. 9-12; Darwin 329)
This is the second course in electronics for the Applied Physics students in the department of Physics and Astronomy. This course primarily focuses on the subject of digital electronics and its applications, and programming of memory devices. A basic knowledge of analog electronics is assumed and will be used especially in the areas of A/D and D/A converters and buffer circuitry necessary for controlling external circuits.
In order to speed up construction and testing of electronic circuits, we will make use of the simulation software "Electronics Workbench" which was introduced in P313/313L. Also an introduction to LabVIEW, an important software tool for instrument simulation and data logging/analysis will be given in this course.
In the last part of the course Programmable Logic Devices will be introduced. In particular, we will program the microcontrollers PIC16C84, and the Basic Stamp BS1-IC. The programmed chips will be used to control lights, servo motors, and other devices as part of the student projects in the laboratory part of the course.
Assessment: There will be four modes of assessment. Written exams, homework, lab performance, and final project. The lab performance assessment will include the quality of the design and implementation of circuits using both simulation software and actual components and equipment. Students are required to design and build projects that have some useful applications.

Test 1, F. Feb. 26 (20%); Test 2, W. Mar. 31 (20%); Final Test*, F. May. 21 (40%) 2-4 PM; Homework (20%).
*The final test consists of two parts: Part I will be on the material covered between the second test and the final (20%), and Part II will be on the entire covered material and will focus on the main topics of the course (20%).
Office Hours: Tue. 10-11:50 AM, Fr. 10-10:50 AM, and by appointment.
Office: Darwin 331, Phone and voice mail: 664-2169
* Students will need to become familiar with the MPASM assembler by Microchip Technology, Inc. if they choose the PIC16C84 chip. Alternatively, the PBASIC assembler by Parallax, Inc. may be needed if the BS1-IC chip is chosen. A slightly different version of MPASM is also provided by parallax for programming the PIC16C84 chip.
I. Laboratory Notebook
Students are required to record the detail of all experiments in a bound laboratory book suitable for digital electronics. The purpose, necessary equipment and the pin diagram of all components should be clearly indicated on the first page of each experiment.
II. Simulation Software
Every experiment should be examined with a simulation software prior to the actual circuit testing. Electronics Workbench is recommended as a suitable software. Students may examine their circuits on either MAC or PC platforms, and their proficiency in using this or any other SPICE-based software will be examined during the initial few weeks of the semester.
III. Final Project
Each student is required to design and build a final project for this course. The final project may be based on a topic covered in the course. The projects should have a clear purpose and application which often includes both digital and analog electronics. Students are encouraged to start choosing their projects at least four weeks before the end of the semester.
The final projects will be presented during the last meeting of the lecture class on Friday, Dec. 12.
The final laboratory grade will be based on (i) laboratory book details (40%), (ii) lab performance (40%), and (iii) the final project (20%)
