A binary PSK system employs two "windowed" sinusoidal waveforms with maximum amplitude A = 1V and frequency for fo21/T with T the symbol period. Let the noise at the receiver input have PSD N,/2=10-º y² / Hz . Determine the maximum channel power attenuation that can be tolerated to guarantee a bit error probability of P =10“ when the bit rate is R, =10kbit/ s , R, =100kbit/s , and R, =1Mbit/s , respectively.
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.
