Abstract
The present invention provides a receiving circuit, wherein the receiving circuit includes a first ADC, an attenuator, a second ADC, a harmonic generation circuit and an output circuit. In the operations of the receiving circuit, the first ADC performs an analog-to-digital operation on an analog input signal to generate a first digital output signal, the attenuator reduces strength of the analog input signal to generate an attenuated analog input signal, the second ADC performs the analog-to-digital operation on the attenuated analog input signal to generate a second digital input signal, the harmonic generation circuit generates at least one harmonic signal according to the second digital input signal, and the output circuit deletes a harmonic component of the first digital input signal by using the at least one harmonic signal to generate an output signal.
