Characterization Of The Rfx400 For Use In Software Defined Radio, Edward Adams
Characterization Of The Rfx400 For Use In Software Defined Radio, Edward Adams
Computer Engineering
While software defined radio is an extremely flexible technology that is fairly rarely used, as a single purpose radio is much cheaper, it provides an excellent means of learning RF and communications skills through the lens of digital electronics, and it would behoove a Cal Poly student interested in these areas to take on a project in software defined radio. This project aims to lower the barrier to entry for future students to undertake such a project. The use of an up-converter/down-converter is documented for future students to interface with.
Fm Radio Receiver With Digital Demodulation, Nicholas Burnett
Fm Radio Receiver With Digital Demodulation, Nicholas Burnett
Electrical Engineering
This paper reports on the design, construction, and testing of an FM receiver. The design is split into two portions, the analog FM front end and the digital demodulator. The job of the front end is to down convert the RF signal to a frequency that is low enough to sample with an analog to digital converter. The construction of the front end is done using what is known as “Ugly Construction.” That is, all the components are soldered together floating over a ground plane.
The second portion of the design is the demodulator. The phase lock loop method of …
