Each week's laboratory exercises in the BSC course are outlined in the laboratory manual. The manual's most up-to-date version is available here. Most of the documents here are in pdf format. If your browser cannot read pdf documents, free pdf readers can be obtained from Adobe.   Note that these labs contain color figures and text and may not print properly if your printer is misconfigured. 

 

The BSC Labs:

Lab 1: Introductory Experiments and Linear Circuits I
These labs introduce you to the equipment you will be using throughout the BSC lab and most of the other labs in Physics 111 and an Introduction to Linear Circuits I.
Lab 1 Appendices: Introductory Experiments and Linear Circuits I Appendices
These are the data sheets on the equipment you will be using.
In the 2nd and 3rd week's lab you will study circuits made from linear components like resistors, capacitors and inductors. Some of the circuits you will build will be filters and resonators. You will learn the concept of impedance and its importance in circuit analysis and electrical measurements. You will also learn why we use scope probes and terminators for scope measurements.

Lab 2: Linear Circuits II

In this week's lab you will continue investigating linear circuits. Fourier analysis, scope probe frequency properties, inductors, resonant circuits, and computer simulations will be studied.
(Also see supplementary material.)

Lab 3: Diodes

This lab begins the study of semiconductor components. You will find the relation between the voltage and current in a diode, and study temperature effects, rectification, nonlinear phenomena, and frequency doubling. (Also see supplementary material.)
Lab 3 Appendices: Diode data sheet and Introduction to Curve Tracer Program Appendices
This is information on parts and programs you will be using.

Lab 4: JFETS I
This lab explores basic JFET characteristics, circuits and applications. You will build a JFET switch, memory cell, current source, and source follower.

JFET Reading: JFETS Reading

Lab 5: JFETS II

This lab investigates some more sophisticated JFET circuits such as voltage amplifiers, differential amplifiers, attenuators, and modulators

Lab 6: Op Amps I

This week's lab studies op amps and feedback. You will construct a comparator, follower, current source, and inverting, non inverting, differential, and summing amplifiers. The lab assumes that the op amps are perfect and uses the Op Amp Golden Rules to analyze the circuits.

Lab 7: Op Amps II

Digital Circuits Reading material for Appendix_1

You will learn about digital circuits, how to use them and when can they be used.

More digital circuits and the 555 Timer chip. (See Data sheet below for 555 Timer chip.)
