The digital echo cancellation circuit determines an echo estimation component according to a digital output signal, and performs a digital echo cancellation on a digital input signal according to the echo estimation component. The parameter control circuit generates a control signal according to the echo estimation component. The analog echo cancellation circuit includes a first echo cancellation resistor and a second echo cancellation resistor, wherein the resistances of the first echo cancellation resistor and the second echo cancellation resistor are adjusted according to the control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication apparatus with echo cancellation and method thereof","description":"A communication apparatus with echo cancellation includes a transmitter, a receiver, a digital echo cancellation circuit, a parameter control circuit, and an analog echo cancellation circuit.
