What is oversampling in ADC?

Oversampling is a popular method to improve ADC resolution. The input is sampled at a rate higher than the minimum required Nyquist sampling rate, fs.

What is oversampling in microcontroller?

As the name implies, oversampling gathers additional conversion data from an input signal. Standard convention for sampling an analog signal indicates that the sampling frequency fs should be at least twice that of the highest frequency component fH of the input signal.

How do I get the best ADC accuracy?

To increase the ADC accuracy, you need to reduce the effects of the ADC-related errors and minimize the ADC errors related to the external environment. The TUE is not the sum of all the errors EO, EG, EL, ED. It is the maximum deviation that can occur between the ideal and actual digital values.

Does oversampling improve resolution error?

Oversampling is capable of improving resolution and signal-to-noise ratio, and can be helpful in avoiding aliasing and phase distortion by relaxing anti-aliasing filter performance requirements.
