CONCLUSION

*First of all, we comprehend the theory of the Amplitude Modulation. This was the first type of modulation used for communicating signals from one point to another and is still the simplest to understand.
*In this project our goal is to build an AM radio Receiver which can work for Medium Wave Frequencies (550kHz – 1600kHz). Medium wave signals have the property of following the curvature of the earth (the groundwave) at all times, and also refracting off the ionosphere at night (skywave). This makes this frequency band ideal for both local and continent-wide service, depending on the time of day.
*After understanding the mathematical expression for the Amplitude Modulation and Demodulation, we started to study physical systems for AM Modulators and Demodulators.
*Then we implemented the circuit as we mentioned before.
