Abstract

See full text

An electronic device includes a processor circuit, a frequency-domain-to-time-domain conversion circuit, a transmitter circuit, a hybrid circuit, a receiver circuit, and a time-domain-to-frequency-domain conversion circuit. The processor circuit generates a frequency-domain transmitting signal. The frequency-domain-to-time-domain conversion circuit converts the frequency-domain transmitting signal into a first time-domain transmitting signal. The transmitter circuit generates a second time-domain transmitting signal. The hybrid circuit includes an echo noise cancelling path and an echo noise path. When the echo noise cancelling path is turned off, the processor circuit receives a first frequency-domain receiving signal. When the echo noise cancelling path is turned on, the processor circuit receives a second frequency-domain receiving signal. The processor circuit determines an echo noise cancelling ability of the hybrid circuit according to the first frequency-domain receiving signal and the second frequency-domain receiving signal.
