Does oversampling increase resolution?

Oversampling and averaging can increase the resolution of a measurement without resorting to the cost and complexity of using expensive off-chip ADCs. This application note discusses how to increase the resolution of analog-to-digital (ADC) measure- ments by oversampling and averaging.

Does oversampling increase SNR?

Oversampling is a cost-effective process of sampling the input signal at a much higher rate than the Nyquist frequency to increase the SNR and resolution (ENOB) that also relaxes the requirements on the antialiasing filter.

How do I increase the resolution of ADC?

Another method for increasing the effective resolution of the ADC is oversampling and decimation. This technique involves oversampling of the input signal so that a number of samples can be used to compute a virtual result with greater accuracy than a single real sample can provide.

What happens when you oversample a signal?

Oversampling reduces or completely gets rid of 3 forms of potential distortion a signal can have: aliasing, clipping, and quantization distortion. Although these forms of distortion are often mild and difficult to consciously hear, they're often noticed when using a lot of processing or pushing a processor harder.
