Abstract:
    The invention relates to a signal processing method, which comprises that: A, amplifying analogue signal according present increment value, to be converted into digit signal; B, reducing said digit signal according to present increment value to be output, and outputting new increment value based on the digit signal, using said new increment value to refresh present increment value when the analogue signal is zero, feeding back to step A. The invention also provides a signal processor, which can dynamically adjust the reduce ratio of input signal according to the amplitude of input signal, to improve the signal/noise ratio.
