  2. Echo suppression and cancellation - Wikipedia

    en.wikipedia.org/wiki/Echo_suppression_and...

    The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3] [9] which is the amount of additional signal loss applied by the echo canceller. Most echo cancellers are able to apply 18 to 35 dB ERLE. The total signal loss of the echo (ACOM) is the sum of the ERL and ERLE. [9] [10]

  3. Adaptive feedback cancellation - Wikipedia

    en.wikipedia.org/wiki/Adaptive_feedback_cancellation

    Adaptive feedback cancellation originated during the evolution of the hearing aid. The hearing aid became digital, and as such feedback cancellation was needed. In 1980 a directional microphone was introduced in the digital hearing aid, and adaptive feedback cancellation was created to block external noise that the microphone picked up. Today ...

  4. Feedback suppressor - Wikipedia

    en.wikipedia.org/wiki/Feedback_suppressor

    Feedback suppressors use several techniques for detecting feedback from non-invasive harmonic analysis of a potential feedback signal to more invasive adaptive filtering and speculative placement of notch filters. The automatic notch technique is the most popular method and has the advantage that the sound is not colored until the system is at ...

  5. Adaptive filter - Wikipedia

    en.wikipedia.org/wiki/Adaptive_filter

    The recording of a heart beat (an ECG), may be corrupted by noise from the AC mains.The exact frequency of the power and its harmonics may vary from moment to moment.. One way to remove the noise is to filter the signal with a notch filter at the mains frequency and its vicinity, but this could excessively degrade the quality of the ECG since the heart beat would also likely have frequency ...

  8. Adaptive noise cancelling - Wikipedia

    en.wikipedia.org/wiki/Adaptive_noise_cancelling

    Adaptive noise cancelling is a signal processing technique that is highly effective in suppressing additive interference or noise corrupting a received target signal at the main or primary sensor in certain common situations where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated, that is, uncorrelated [1] [2] [3].
