Preventing acoustic feedback in the microphone circuit |
摘要 |
This method deals with the suppression of the feedback whistle frequently occurring in microphone transmissions. This is done by limiting the amplitude of the microphone signal when a sine wave rising above the useful signal is detected. From this rise, a control voltage is formed which limits the gain at this point. This prevents feedback from arising.
