The goal of this project was to gain a deeper understanding of how Amplitude Modulated (AM) radio waves are received, demodulated and amplified to output music. To do this, we attempted to build our own AM radio receiver using breadboard components and an antenna made from scratch out of ferrite and copper wire. We combined resonant capacitors and inductors to create an antenna system capable of efficiently capturing and channeling electromagnetic radio waves. We tried different systems with components including transistors, diodes, and op-amps to demodulate the received signals, extract the underlying audio information, and amplify it into a discernible output. Though we did not achieve our goal of constructing a functional AM radio receiver, we deepened our understanding of the principles of its operation through hands-on experimentation and design.
