  • Quadrature Amplitude Modulation: Modulator and Demodulator
    • 1. Quadrature amplitude modulation Aside from increased channel capacity, QAM has various other advantages, which are stated below.
    • 2. One of the most significant advantages of QAM is its ability to sustain a high data rate. As a result, the carrier signal can carry a certain amount of bits. Because of these benefits, it is preferred in wireless communication networks.
    • 3. The noise immunity of QAM is quite strong. Noise interference is a bit low as a result of this.
    • 4. It has a low mistake probability value.
