Abstract:
A signal modulation method by an electronic device which includes a minimal reducing unit that minimally reduces an integrated signal returned to an adder from an integrator.The signal modulation method includes generating an added signal with the adder. The signal modulation method further includes generating a new integrated signal with the integrator by returning a previously self-generated and stored integrated signal to the adder, and by integrating the added signal generated by the adder.The signal modulation method further includes generating a new quantization signal with a quantizer by quantizing the new integrated signal generated by the integrator.
