Laboratories

Labs will be posted here on Monday morning and are due in Glennan 308 during assigned lab periods, one week after they are assigned.

IMPORTANT LAB MESSAGE

Second Order LowPass Filter Analysis . These notes show the derivation of the frequency response for thefirst and second order lowpass filters used in Lab #12 (Figures 4 and 5).

Lab 12 (This lab will be done in Glennan 308 during April 11-13. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during class Wednesday April 20th.). This lab will measure the magnitude and phase response of active filter circuits as a function of frequency. This lab is the last lab of the semester!

BandPass Filter Analysis . These notes show the derivation of the frequency response for the bandpass filter used in Lab #11 (Figure 6). The analysis is complicated because the two filter sections (a lowpass and a highpass) cannot be electrically separated from each other.

Lab 11 (This lab will be done in Glennan 308 during April 4-6. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section April 11-13). This lab will examine the frequency dependence of capacitors and inductors in simple circuits. You will construct simple filter circuits and measure the magnitude and phase response of these circuits to sinusoids of various frequencies.

555 Lecture Notes (These are lectrure notes describing the internal structure of the 555 (essentially two comparaors and a switch) and show how to perform 555 timing calculations based upon your knowledge of exponential waveforms.

Lab 10 (This lab will be done in Glennan 308 during March 28-30. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section April 4-6). This lab introduces you to one of the most popular integrated circuits -- the 555 timer. You will use it as a one-shot (a popular circuit for removing noise from electrical signals), an oscillator, and a water level sensor.

Lab 9 (This lab will be done in Glennan 308 during March 21-23. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section March 28-30). This lab will introduce you to the experimental measurement of RC time constants for exponential waveforms using a digital oscilloscope.

Lab 8 (This lab will be done in Glennan 308 during March 14-16. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section March 21-23). This lab will introduce you to non-linear OP AMP circuits of which the comparator discussed in class and homework is one. In this lab you will build a comparator circuit using an OP AMP, measure its performance for signals with and without noise, and examine the performance of another circuit, the Schmitt trigger, for cleaning up noisy signals.

Lab 7 (This lab will be done in Glennan 308 during February 28-March 2. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section March 14-16 - AFTER SPRING BREAK). This lab will introduce you to the integrated circuit OP AMP. In this lab you will learn how to power the integrated circuit OP AMP, construct simple inverting and non-inverting amplifier circuits based upon the OP AMP, and measure their operating characteristics.

Oscilloscope Probe Manual . This document describes the electrical behavior of the oscilloscope probes used in the circuits lab.

Lab 6 (This lab will be done in Glennan 308 during February 21-23. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section February 28-March 2). This lab introduces you to two of the most important instruments you can use to generate electrical test signals (the function generator) and the device which you can use to measure the time dependent behavior of circuits (the oscilloscope). THIS LAB HAS NOT BEEN CHECKED BY THE TA'S.

Lab 5 (This lab will be done in Glennan 308 during February 14-16. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section February 21-23). You will construct a linear circuit of eight elements (two voltage sources and six resistors); measure the i-v characteristics of this circuit at several output points, and determine the Thevenin equivalent circuit for each output.

Lab 4 (This lab will be done in Glennan 308 during February 16-18. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section February 7-10). You will construct a linear circuit of nine elements; measure the DC currents and voltages in the circuit; and validate Kirchoff's Laws and the superposition property for this linear circuit.

Lab 3 (This lab will be done in Glennan 308 during January 31-February 2. The corresponding lab write-up (ONLY ONE PER GROUP) will be due during your lab section February 7-9). This lab covers using LabVIEW to make very simple voltage measurements using a suitably equipped computer and comparing these measurements with the same measurements made using a Digital MultiMeter.

Lab 2 (This lab will be done in Glennan 308 during January 24-26. The corresponding lab write-up - ONLY ONE PER GROUP - is due during your lab section January 31-February 2). This lab covers basic LabVIEW programming concepts. Although we will not use LabVIEW extensively in ENGR 210 it is commonly used by biomedical, chemical, mechanical and most other engineers in industry. NOTE: Monday laboratory groups will have a short orientation( at the beginning of this week's lab section) to the lab and assignment of partners to make up for the lab missed last Monday.

Lab 1 (Lab write-up is due during your lab section January 24-26). This lab may be done by downloading the lab software (see below or read the lab for more details) to any Windows or Mac computer. Reports are to be done individually and turned in during regular lab sections during January 24-26.
