The ADC’s sampling rate, also known as sampling frequency, can be tied to the ADC’s speed. Two important aspects of the ADC are its sampling rate and resolution. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. This is because microcontrollers can only see “levels” of the voltage, which depends on the resolution of the ADC and the system voltage.ĪDCs follow a sequence when converting analog signals to digital. Microcontrollers can’t read values unless it’s digital data. (Source: Waqas Akram – Quantization in ADCs) The easiest way to explain this it through a visual! Figure 1 shows a great example of what analog and digital signals look like.įigure 1: A continuous signal (analog) turning into a digital signal. Digital signals are represented by a sequence of discrete values where the signal is broken down into sequences that depend on the time series or sampling rate (more on this later). These types of signals can come from sound, light, temperature and motion. In the real world, analog signals are signals that have a continuous sequence with continuous values (there are some cases where it can be finite).
