Our Project

Project Description

At present, the angular position of a rotating instrument is measured with a resolver. The output of a resolver is unintelligible to a computer, so a resolver-to-digital (RDC) converter is needed. This translates the resolver signal into machine-readable language. There are two customers for this SDP project: L3 Harris KEO and the UMass Amherst MIRSL Lab. For L3, this project will be an RDC proof-of-concept. For MIRSL, the project will be a flexible system to quickly and accurately convert any resolver signal for use in weather radar tracking. Attached to a single or dual resolver, the final product will output a measured angle to the user over multiple communication methods.

Jacob Andrade

My name is Jacob Andrade and I'm from Lowell, MA. I'm majoring in electrical engineering but also have a strong interest in computer engineering. I currently work at DellEMC in Hopkinton on their Platform Hardware Engineering team and will return there after graduation to start full time. In my free time I enjoy skiing and going to the gym.

Meg Hardin

Hello, my name is Meg Hardin, and I'm a senior electrical engineering major at UMass Amherst. I started my academic career studying biology, and became interested in signal processing and electrical engineering while working as a research assistant measuring electrical signals from the human body. Since changing my major, I've realized that ECE is huge field with so much to learn! Over time, I specialized my studies toward digital systems and the semiconductor design/release process. Next year, I will be working for Analog Devices as a Product and Test Engineer. Outside of class, you can find me knitting or working on my fish tank.

Wayne E Hobby

I'm an Electrical Engineering Major, currently specializing in Microwave Engineering and Electromagnetics. I'm taking the lead in the analog circuitry for the project, especially the PCB Layout where my skills can be put to good use. Outside of school, I'm employed at Bruno's Pizza on Main St, and I have an internship at L3Harris KEO. I also enjoy hiking in the surrounding area, and spending quality time with a good book or a woodworking project.
