Review Questions

Homework

These are recommended problems to prepare for the exams. This will not be collected or graded, but many of these questions will be used for the Midterms and Final. It is necessary to get practice with these problems and it is strongly encouraged to start as soon as possible in order to have plenty of time to get help, ask questions and prepare.

Supplies

Throughout the semester you will need a few lab supplies. Here is a tentative list and some sources or recommendations.

Most supplies can be purchased from the EAT – Embedded Applications Technology Club located in VEC-524. Just walk in (They are usually available throughout the day) and ask for the EAT club. All of their supplies are competitively priced with no waiting/shipping times and the club is a great resource to join and get ahead in your career.

Digital Multimeter – Not carried by EAT, have a look at my dedicated multimeter page for some discussion and recommendations.

Resistor Pack – Resistor Assortment of 1/4 or 1/8 watt with various values. EAT has gone through the trouble of assembling all of the necessary values that would be useful for the rest of your academic career. Keep in mind that this is a starting point, you will definately grow your collection as you learn. You can get this from EAT, amazon, or ebay. As for the different values you will need, all I can say is many different values. If you have a look at the class supplies page, you will see a link for a variety pack of 56 different values. Something like that will serve you well for the remainder of your classes in this department.

Breadboard – You will need a way to prototype your circuits. A breadboard will allow you to do this. For a picture of what a breadboard is, you can check out this link Breadboard. There are a few different standard sizes, any of them will work. EAT has these as well. A good recommendation for a size is 830 connection points, approximately 2.2″ x 7″ but a smaller one will work just as well.

Wire and Wire Strippers or Jumper Wires – There are two ways to connect circuits on a breadboard. You can buy already made jumper wires, like: or  or you can buy a roll of wire and use wirestrippers to cut your own length  and 

Check out the supplies page more more discussion on wire strippers. The recommended wire size for breadboards is 22 awg solid core wire and similarly the wire strippers should match the wire size, 20-30 awg is the right range for us. I prefer the greenlee P20. EAT also carriers wire for making connections.

Toward the end of the CECS 211 semester and continuing through CECS 311 and well into CECS 262, 346, 347, 447 and into the Senior Design 490A/B classes there are other supplies you will want eventually.

Capacitor Pack – Assorted Electrolytics and Ceramics

Oscilloscope Probes x2 – for the Oscilloscopes in lab

BNC to Alligator Clip Cable – for Function Generators

311 Parts Kit – various components we will use in 311
