Team 302: Frequency Multiplier
Independant, Affordable and Programmable
Demonstration
Abstract
The signal generator and oscilloscope are the heart and mind of electrical engineering. Used to create and read signals respectively, both are vital for learning and real-world testing. However, limitations in both cost and usability limit these devices. Costing thousands of dollars, not having matching ranges, and requiring manual adjustments all hinder any level of use case. Our project hopes to solve these problems by creating a signal generator that can cover most oscilloscope ranges for under a hundred dollars, as well as automate the process of testing through a computer program.
There are two major parts to our project, the physical multiplier, and the computer controls. The multiplier can take in a user input and can output a faster version of an input signal. It can also work independently, creating a signal of any value within range. The computer controls can also set a multiplication value or set signal but can also run an automated test through a range of signals. In addition, all the data can be viewed on the computer user interface, as well as saved locally. Whether it be students, hobbyists, paid professionals, or kids; this project makes electrical engineering easier and more affordable.
Bode Plotting
A bode plot is a combination plot that observes the magnitude and the phase difference between two signals over numerous frequencies, which is a vital tool for electrical engineering. The ability to observe how a system reacts to different signal levels is extremely versatile, both for professional applications and for teaching the basics of the field. As time went on, a major aspect of the project became getting a working Bode Plot application as a function of our computer controls. While the DSOX1204G has a robust Bode system built in, we have to start from scratch due to how our multiplier works. Our current system is able to replicate Bode Plots made using the built in system, as well as utilize the full range of the read in system for the Oscilloscope, and can be utilized with systems that do not have access to built in Bode systems.
