What is Noise shaping?
A technique that uses a feedback loop to push quantization noise toward high frequencies, lowering noise in the signal band. Delta-sigma ADCs combine it with oversampling to achieve high resolution.
Field: AD/DA conversion
Noise shaping in the explanations
ΔΣ converters add noise shaping to obtain far greater improvement.
With simple oversampling and no noise shaping, how much doe…A ΔΣ ADC samples far above the signal bandwidth (oversampling), uses a feedback loop to push quantization noise to high frequencies (noise shaping), and removes it with a digital filter.
Which is a characteristic of a delta-sigma (ΔΣ) AD converte…
