Quantization Error and SNR

In earlier posts, we had a glimpse of the term quantization error. This error is introduced during the quantization process in the due course of conversion. The process of quantizing is equivalent to rounding up or truncation of a number. Incase of analog converters, it is the rounding up/truncation of the analog signal to a digital value the ADC can output (or encode). This process of approximation introduces an error called the quantization error into the readings. It other words the errored output is the result of infestation (superimposition) of quantization noise on the input signal. Continue reading Quantization Error and SNR
