WEEK

(I stumbled across an interesting number system that has been proposed as an alternative to the binary number system used in computers balanced ternary. (Not required reading))

 

This week we will start our final project.

GOALS:

 

To complete the final project the students will need to draw on the experiences accumulated throughout the semester. You notes should be helpful because parts of the final circuit were built in earlier classes.

In order to build a complicated circuit it is wise to consider the following points:

At the start of the project the students will be doing most of the debugging. Therefore when you need help be sure that you have done the routine troubleshooting.

 

Comment on electronic diagrams.

Diagrams are general tools for displaying information. Many of the aspects of the diagrams used in the electronics lab are found in diagrams for very diverse problems. Most people will need to be able to read and understand diagrams. In trying to understand a diagram it is useful to place your finger on the diagram and follow a path noting where you end up. For example, starting at 5 V, you go through a resistor and arrive at pin 1 of an IC and also at another resistor. Now complete the same exercise on the your circuit and ask if the above observation has been successfully reflected in the circuit. For some this remains a difficult task. Perhaps if you imagine the starting point as the hot dog stand in a park, the components as bridges, wires as sidewalks, and IC pins as specific locations in the park, the logic of the diagram will be more understandable. Examine the diagram below.

 

 

 

 

The electronic diagram on the left is similar in content to the diagram on the right. You would not assume that all paths in the park were straight. You would not assume that the distances were necessarily precise but you would expect it to be necessary to cross a bridge when going from the hot dog stand to the playground. After you cross the bridge you would expect to be able to proceed to another bridge or to proceed to the playground. Try to relate the important information shown in both diagrams.

 

QUIZ *******

 

QUIZ *******

In order to receive a grade of A you must successfully complete the lab portion of the course, read prelab material, and pass the lab quiz. In order to pass you must get 75% of the questions correct.

In order to receive a grade of B you must successfully complete the lab portion of the course. The quiz is optional. For fun feel free to try the quiz.

You are not allowed to consult with other students while taking the quiz. You will be given a limited time period to complete the quiz. You may refer to any written material.

You may take the quiz at any time during the week but only once.

The quiz will be available starting on the day you cover the material and ending one week later.

 If you have troubles please discuss the difficulties with DRG.

You are not allowed to consult with other students while taking the quiz. The quiz will be available at least from lab until following lab. You will be given 30 minutes to complete the quiz and you may refer to any written material.
