Question 6: 1- List the pins on Arduino that can do analog write. 2- In a PWM, given that the duty cycle is 80% what is the voltage output? 3- In a PWM, what should be the duty cycle to get a voltage output of 4.5 V? 4- Given the bellow Arduino command: analogWrite( 8, 200); a- What is the duty cycle? b- What is the voltage output?
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.
