A door sensor is connected to PO.5 pin, an LED to P1.5 pin and a buzzer to P2.5 pin. VWrite an 8051 C program to monitor the door sensor such that when it is opened, the LED will blink and the buzzer will sound every 500ms, otherwise, when the door is closed, both of the LED and buzzer will be OFF.
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.
