Section 4 Review Quiz and Answer Key

 

In class, we wrap up the Section 3 review quiz and then start our introduction on integrated circuits.

 

In this class, we build Activity 1 using the 555 IC to make a tone generator.

Homework: Ensure that you have Activity 1 working and have it ready for the next class.

 

In this class, we review Activity 1 and then build Activity 3, which demonstrates a one-shot timer.

Homework: Draw the schematic for Activity 1 and then build the activity following the schematic. Be sure to double check your connections against the breadboard picture.

Optional: Build Activity 2, which demonstrates the charging and discharging of a capacitor.

 
In this class, we continue our discussion of Activity 3 and learn more about the 555 IC and the concepts of frequency and duty cycle.
 
In this class, we build Activity 5 and learn more about astable multivibrators
 
In this class, we build Activity 5, which demonstrates how to generate multiple frequencies.
 
IN this class, we review the circuit for Activity 5. We then discuss dual power supplies and build Activity 6.
 
In this class, we build Activity 7 using the 741 operational amplifier.

 

 
In this class, we review Activity 7 and learn more about operational amplifiers. We also learn the difference between inverting and non-inverting configurations for an op-amp.
 
Homework: Rebuild Activity 7 by following the schematic.

 

In this class, we build Activity 8 using a JFET. We then learn more about Field Effect Transistors.

Homework: 
1) Build Activity 8 on your own
2) Draw a schematic of Activity 8 by following your breadboarded circuit
3) Draw the schematic symbols for JFETs and MOSFETs

 
In this class, we complete the Section 4 review quiz.
