transferring information signals to the amplitude of ahigh-frequency continuous-wave carrier. The modulated AM waveform can be described by ‫ݏ‬ሺ‫ݐ‬ሻ = ሾ‫ܣ‬௖ + ݉ሺ‫ݐ‬ሻሿ cosሺ2ߨ݂௖ ‫ݐ‬ሻ, (1)where Ac is the carrier amplitude, m(t) is the arbitrary message signal, and fc is the carrierfrequency. As a result of the modulation property of the Fourier transform, the signal spectrumis given by ‫ܣ‬௖ ܵሺ݂ሻ = ሾߜሺ݂ − ݂௖ ሻ + ߜሺ݂ + ݂௖ ሻሿ + ‫ܯ‬ሺ݂ − ݂௖ ሻ + ‫ܯ‬ሺ݂ + ݂௖ ሻ, (2) 2where the carrier spectrum is composed of two Dirac delta functions at ±fc and the messagesignal spectrum is translated to ±fc.Creation of the AM
