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 demodulating FM signals is used. The phase lock loop demodulator is designed in the digital domain on an FPGA. The design approach used for the demodulator is a digital hardware implementation using VHDL.
