METHOD AND APPARATUS FOR ANALOG-TO-DIGITAL CONVERSION |
摘要 |
A method for analog-to-digital conversion includes the steps of applying a first transfer function to the input signal and amplifying the input signal by a defined gain factor to obtain an edited signal, subject chronologically successive samples of both the input signal and the edited signal to analog-to-digital conversion and thereby obtaining digital data having a defined number of bits corresponding to the input signal and digital data having a defined number of bits corresponding to the edited signal, multiplying the digital data corresponding to the input signal by a defined factor equal to the gain factor, applying a second transfer function to the digital data corresponding to the input signal by digital filtering, and undertaking calculations on the signals obtained in this manner to obtain a final analog-to-digital conversion result. An apparatus operating according to this method is also disclosed.
