WebThe modulator output has only 1-bit (two- levels) of information, i.e., 1 or -1. The modulator out- put y(n) is converted to xt() by a 1-bit D/A converter (see Figure 6-4). The input to the integrator in the modulator is the difference between the input signal x(t) and the quantized output value y(n) converted back to the predicted analog signal, x(t). Web3. Carrier Modulation – Analog Modulation is the process of using an information signal (such as voice or music) to alter some property of a higher frequency waveform which can then be efficiently radiated by reasonably small antenna. Waveforms at different “radio” frequencies can simultaneously “carry” a plurality of information signals.
