A carrier wave is amplitude modulated by a message signal. Their respective expressions are provide below. Determine the modulation index of the modulated waveform carrier = 10cos(2pi x 106)t; message signal = 3cos(2pi x 100)t + 4cos(2pi x 1000)t
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
