Abstract:
1. A method for translating an analog signal to a digital signal, comprising: sampling said analog signal from an input terminal; converting said analog signal to an N-bit digital signal; comparing said N-bit digital signal with a previously selected N-bit digital signal, and recording “X” in said 1-bit storage unit when said N-bit digital signal is larger than said previously selected N-bit digital signal, recording “Y” in said 1-bit storage unit when said N-bit digital signal is less than or equal to said previously selected N-bit digital signal, wherein “X” and “Y” are digital numbers; and selecting said previously selected N-bit digital signal if said N-bit digital signal is 1-bit smaller than said previously selected N-bit digital signal and said 1-bit storage unit contains “X”, and selecting said N-bit digital signal in all other cases.
