AM Modulation

There are three different types of modulation techniques can be used for this project such as AM, FM and PCM modulation. These can be digital or analog but we have to be careful with the bandwidth. Because the analog system can have a limitation and therefore the digital system is more suitable for this project. Amplitude modulation is where the amplitude of high frequency carrier wave is changing with the intensity of the signal and it is much simpler to design. But have a Bandwidth limitation which is not the best solution for this project.
