Device and method for noise suppression |
摘要 |
An analog signal is sampled to provide a digitized signal and the resultant digitized signal is output to a delay element, which provides a delayed digital signal. The analog signal is also input to an analog noise detector, which provides a noise detector output signal to a digital logic unit. The digital logic unit processes the noise detector output signal to determine if noise is present in the analog signal, and provides a control signal. An amplifier receives the delayed digital signal and reduces a gain applied to the delayed digital signal in response to the control signal, and provides an amplifier output signal.
