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 the purpose of oversampling?

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. A signal is said to be oversampled by a factor of N if it is sampled at N times the Nyquist rate.

What does oversampling do in a DAC?

Oversampling Interpolating DACs use interpolation to achieve a higher resolution output than provided on their input. This allows less complicated output filtering for a DSP system operating close to its Nyquist rate.

What is called oversampling?

Over sampling is used when the amount of data collected is insufficient. A popular over sampling technique is SMOTE (Synthetic Minority Over-sampling Technique), which creates synthetic samples by randomly sampling the characteristics from occurrences in the minority class.
