Amplitude Modulation (AM)

by Emona Tims

In this lab, students will create an amplitude modulated signal from a variety of message sources, calculate the modulation index, and confirm the frequency spectrum of this signal type. Designed for...
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.
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.
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...
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 7: Amplitude-Shift Keying

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

In this lab project, design of the transmitter and design of the receiver each present challenges and opportunities for investigation.
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 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.
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.
Lab 5: Double-Sideband Suppressed-Carrier

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

This laboratory exercise introduces suppressed-carrier modulation.
