Abstract:
1. An Analog/Digital (A/D) modulation apparatus with a Nyquist structure, the A/D modulation apparatus comprising: an A/D modulation module having a structure in which a plurality of unit loops are extended by a serial connection, the A/D modulation module being configured to receive an initial analog signal and output individual digital-modulated signals for the plurality of unit loops; a control module configured to determine a modulation resolution that is needed in order to use a communication mode, and configured to output modulation control bits to obtain the determined modulation resolution; a signal transfer control module including an input control module configured to transfer or block an intermediate output signal of a basic loop, to which the initial analog signal is input, from among the plurality of unit loops, as an input signal of an extended loop serially connected to the basic loop, in response to the modulation control bits provided from the control module; and an output module configured to generate a final digital-modulated signal based on a final output signal of the basic loop and a final output signal of the extended loop.
