) and 1. This is an analog world.Some examples of analog data inclu pitch and volume of music the colors of a painting, or the phases of th moon. Analog data can be closely approximated digitally using a sampling technique, which means measuring values of the analog signal at regular intervals called samples. The samples are measured to figure out the exact bits required to store each sample. Watch the video and answer the following questions. 1. How is a digital representation of analog data a form of abstraction? 2. Why is the quality of the photo music, etc better when more samples are taken? 3. Music is an example of analog data What others examples of analog data can you think of?

1. A digital representation of analog data is a form of abstraction because it simplifies the continuous and complex nature of analog data into discrete values. By using a sampling technique, the analog signal is measured at regular intervals, and these measurements are used to determine the exact bits required to store each sample. This process of converting continuous data into discrete values is an abstraction, as it simplifies the representation of the data while still retaining its essential characteristics.2. The quality of the photo, music, etc., is better when more samples are taken because it results in a more accurate representation of the original analog signal. By increasing the number of samples, the digital representation can capture more details and nuances of the analog data. This leads to a more faithful reproduction of the original signal, resulting in better quality.3. Other examples of analog data include temperature, light intensity, sound waves, and the position of an object. These examples, like music, are continuous and can take on an infinite number of values within a given range. They can be measured and represented using analog signals, which can then be digitally approximated using sampling techniques.
