First, a test signal may be sent through an echo cancellation pathway during a downstream silence period and an upstream silence period. The echo cancellation pathway may comprise an electronic element. Next, a loopback response signal may be received in response to sending the test signal through the echo cancellation pathway. Then a channel response model may be created that characterizes a channel response of the loopback response signal and a non-linear model may be created that characterizes a non-linearity of the electronic element. Next, for a downstream signal, a non-linear component may be generated based on the created non-linear model. The generated non-linear component may be convolved with the created channel response model. The convolved non-linear component may then be subtracted from an upstream signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Analog echo cancellation with digital-to-analog converter noise suppression","description":"Analog echo cancellation with Digital-to-Analog Converter (DAC) noise suppression may be provided.
