Lesson 20: Analog to Digital Converter (ADC)

ADCs are peripherals that convert a continuous analog voltage to a discrete digital number. In order to convert to digital, the signal is sampled at higher frequencies to minimize signal loss. Then the amplitude at those sampled moments is converted with respect to their quantization level. Finally, these levels and moments are entitled to a unique code, which is simply the combinations of 0's and 1's – this is called encoding.
