Title

AM Radio Receiver Using the RTL-SDR

Description/Abstract/Artist Statement

Software-defined radios are a modern method that removes the reliance on hardware to demodulate radio signals. One of the versions of these software-defined radios is the RTL-SDR. These devices have limitations on the frequencies that they are capable of modulating. The AM radio frequencies are part of this bandwidth that is inaccessible to the SDR to utilize without additional circuitry. To make these frequencies available to the RTL-SDR, a frequency upconverter will be designed and built to shift the AM radio signal into a high enough frequency for the RTL-SDR to demodulate the signal. After the AM frequencies are shifted into a usable range, MATLAB’s Simulink program will then be used to convert the signals into audio.
