FFT and Spectra

by Emona Tims

In this lab, students will investigate the frequency spectrum of common signals by using the FFT mode of the Oscilloscope and relate this to the signals in the time domain
FM Demodulation

by Emona Tims

In this lab, students construct a demodulation process that translates the frequency variations of a frequency modulated signal into voltage variation in a linear manner. Designed for NI ELVIS III.
Lab 8: Frequency-Shift Keying

by Dr. Bruce Black | Rose-Hulman Institute of Technology

In this lab, students will learn about the benefits of frequency-shift keying.
FSK

by Emona Tims

In this experiment, students will implement the VCO method of generating an FSK signal, and then recover and analyze the data.
Binary Phase Shift Keying (BPSK)

by Emona Tims

In this lab, students will generate a BPSK signal, and then recover the data using product demodulation. They will observe the message distortion and use a comparator to restore the data. Designed...
Lab 5: Double-Sideband Suppressed-Carrier

by Dr. Bruce Black | Rose-Hulman Institute of Technology

This laboratory exercise introduces suppressed-carrier modulation.
Introduction to the EMONA Communications Board

by Emona Tims

In this lab, students will become familiar with the relationship between block diagrams and the circuit modules that will enable them to learn communication systems. Designed for NI ELVIS III.
Lab 11: Equalization

by Dr. Bruce Black | Rose-Hulman Institute of Technology

In this lab project, students will use the BPSK transmitter and receiver created in Lab 9 and the Channel.gvi used in the eye diagram lab project to investigate an equalizer provided in the...
Lab 10: The Eye Diagram

by Dr. Bruce Black | Rose-Hulman Institute of Technology

In this lab project we will examine how the eye diagram changes when intersymbol interference (ISI) is present in the communication channel.
Lab 3: Frequency-Division Multiplexing

by Dr. Bruce Black | Rose-Hulman Institute of Technology

In this laboratory exercise you will investigate sending multiple messages on a single carrier by frequency-division multiplexing.
