K123 is light intensity measurement sensor. The sensor can measure from no light to 1000 Lux. Sensing element is a light dependent resistor with a sensing area of 2 mm?. It is operated with 5V supply. The output voltage is ground level for no light and 5V for a maximum illumination. The sensor can measure 1 lux changes accurately. 26- Find Input range. 27- Find Input span. 28- Find output range. 29- Find output span. 30- Find the output sensitivity. 31- Classify the transducer in terms of transducer classification, use the transducer classification table and classify for each branch.
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.
