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.
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.
Soldering Techniques: Learn to Solder connections and wires


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.)

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

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

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.

In this week's lab you will continue your study of ideal op amp circuits. Circuits to be constructed include a current to voltage converter, a NIC (negative impedance converter), a gyrator, and an oscillator. The lab ends with the construction of a complex circuit that calculates root mean squares.

In many circuits, op amps behave perfectly in the sense that the op amp golden rules are obeyed. However, some circuits expose op amp imperfections which violate the golden rules. This week's lab explores these circuits, and investigates methods of curing some of the imperfections. (Also see supplementary material.)
