Adaptive filtering is described for use with amplifiers for any wired speaker. In one example, an apparatus includes an audio cable to provide an analog audio signal to an audio transducer, such as a speaker, the audio cable also receiving a modulated noise current, an output amplifier to receive an audio input, to generate an audio output by amplifying the audio input, and to provide the audio input to the audio cable, and a feedback system to receive the audio output and to receive a reference signal and to generate a noise cancellation signal to the output amplifier, the noise cancellation signal to cancel the modulated noise current.

Method and apparatus to control delay between lanes in an I/O interface is disclosed. To control the delay between the lanes in the I/O system a programmed delay may be determined and introduced between the lanes. For this purpose the effective time 'T' of the lanes is determined. The number of lanes 'N' in the I/O interface is identified. The programmed lane to lane delay &#x201c;D&#x201d; is determined and a delay circuit having the programmed delay may be introduced between the lanes to reduce AC peak to peak noise in the I/O system.
