Abstract
A signal processing system for changing a level of an input signal to generate an output signal is disclosed. The signal processing system includes a shifter, a sigma-delta modulator, and a level adjuster. The shifter is utilized for receiving the input signal and for bit-shifting the input signal according to a first predetermined gain to generate a first adjustment signal. The sigma-delta modulator is utilized for generating the output signal according a second adjustment signal and the first adjustment. The level adjuster is utilized for adjusting a level of the output signal according to a second predetermined gain to generate the second adjustment signal.
