Consider a 7-cell system covering an area of 4800km2. The traffic in the seven cells is as follows: Cell 1 2 3 6 7 number Traffic 30.8 66.7 46.8 33.2 38.2 32.6 37.2 (Earlangs) Each user generates an average of 0.04 Erlangs of traffic per hour, with a mean holding time of 120s. The system consists of a total of 395 channels and is designed for a grade of service of 0.025. a. Determine the number of subscribers in each cell. b. Determine the number of calls per hour per subscriber. c. Determine the number of calls per hour in each cell.

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.
