Abstract
One signal processing apparatus includes a sigma-delta modulating block and a notch filtering block. The sigma-delta modulating block is arranged to perform a sigma-delta modulation upon a signal input and accordingly generate a signal output. The notch filtering block is arranged to perform a notch filtering operation upon the signal output for generating a filtered signal output. Another signal processing apparatus includes a sigma-delta modulating block and a notch filtering block. The sigma-delta modulating block is arranged to perform a sigma-delta modulation upon a signal input and accordingly generate a signal output. The notch filtering block is enabled for performing a notch filtering operation upon the signal output when the signal processing apparatus operates in a first operational mode, and the notch filtering block is disabled when the signal processing apparatus operates in a second operational mode.
