Converting Analog Data to Binary, Sampling, Quantization - AP Computer Science Principles

Описание к видео Converting Analog Data to Binary, Sampling, Quantization - AP Computer Science Principles

Strap in, this one's gonna get a bit bumpy.

Converting from analog data to digital is a three step process. "Sampling" involves taking a sample of points from a continuous curve, such as a sound wave. Once the points have been selected, their values must be rounded off in a process called "quantization." Finally, these approximated values are further simplified, then converted into binary.

As you watch, keep these two facts in mind:
1) Analog data is infinite, digital is finite.
2) Lower intervals mean higher fidelity, but also a larger file.
