Final answer:

Acoustic echo cancellation is a DSP technique used to remove echoes from audio signals by analyzing and subtracting the echo signal. It relies on the principle of destructive interference.

Step-by-step explanation:

Acoustic Echo Cancellation

Acoustic echo cancellation is a digital signal processing (DSP) technique used to remove echoes from audio signals. It is commonly used in telecommunications, video conferencing, and audio recording systems to improve sound quality.

The process of acoustic echo cancellation involves analyzing the incoming audio signal and identifying any echoes. The system then generates an estimate of the echo and subtracts it from the audio signal, effectively canceling out the echo.

Acoustic echo cancellation relies on the principle of destructive interference, where the echo signal is combined with an attenuated version of the original signal, resulting in a cancellation of the echo. This allows for clear and echo-free communication.
