    Relationships between bandwidth, Fourier trans & digital modulations

    Well, in that case, I guess this is an expert question on a transceiver system. No wonder the book has a considerable gap between the FFT explanation and digital signal modulation. Does anyone have a pointer to understand the matters within the gap?

    Relationships between bandwidth, Fourier trans & digital modulations

    HiHo! W. Stallings's "Wireless Communications & Networks, 2nd edition" explains the relationships between bandwidth and Fourier transformation by depicting a square wave. The square wave is approximated with a Fourier series having several sine terms. The bandwidth is then defined by the...
