<p>Provided is a method for transmitting a signal, which can lower the sampling rate requirements of a digital-to-analogue converter at low costs so as to reduce the costs of communication devices and network construction. The method comprises: acquiring, by a sending end, a target digital signal required to be sent to a receiving end; determining, by the sending end, a target DAC corresponding to a target frequency band from the at least two DACs, wherein the target frequency band is a frequency band used by the sending end and the receiving end to communicate, and the target frequency band belongs to a characteristic Nyquist domain corresponding to the target DAC; processing, by the sending end, the target digital signal via the target DAC so as to generate a target analogue signal; and sending, by the sending end, the target analogue signal to the receiving end through the target frequency band.</p> |
