Super-heterodyne Receiver

Designed and simulated a complete Frequency Division Multiplexing (FDM) Communication System using a Superheterodyne Receiver architecture. The project combines three audio stations using different modulation techniques (DSB-LC, NBFM, and DSB-SC), then implements RF filtering, frequency mixing, Intermediate Frequency (IF) filtering at 25 kHz, and individual demodulation techniques to recover the original audio signals.

The project demonstrates practical Digital Signal Processing (DSP) concepts, including modulation, multiplexing, filtering, frequency conversion, and demodulation.
