Modeling Equations

by Emona Tims

In the lab students will investigate the addition of two signals and compare the theoretical calculation with measured results. Designed for NI ELVIS III.
In this lab, students will recover a variety of messages from an amplitude modulated carrier signal and develop an understanding of the demodulation process. Designed for NI ELVIS III.
In this lab students use the Emona Communication board to learn two methods for amplitude modulation (AM) demodulation. Designed for NI ELVIS III.
Students will create a DSBSC signal and gain insight into the meaning of ā€œSuppressed Carrier," and use product demodulation to recover the message and examine the effect of phase and frequency...
FM Modulation

by Emona Tims

In this lab, students will generate a frequency modulated signal using a variety of message sources, measure the power and bandwidth, and calculate the frequency deviation of the modulator circuit....
Lab 2: Amplitude Modulation

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

This laboratory exercise has two objectives: to gain a firsthand experience in actually programming the USRP to act as a transmitter and a receiver, and to investigate classical analog amplitude...
Students will generate an SSB signal by implementing the mathmatical model for the phasing method, and then use a product detector (with a stolen carrier) to recover the message. Designed for NI...
Lab 9: Binary Phase-Shift Keying

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

(1)
In this lab, students will learn about binary phase-shift keying, where one binary data value is represented by an unmodified carrier, while the other is represented by an inverted carrier.
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 which translates the frequency variations of a frequency modulated signal into voltage variation in a linear manner. Designed for NI ELVIS III.
