Abstract
Described is an apparatus comprising: a first sampler to oversample a signal, the signal being processed for transmission through a channel having a notch region; a bandpass filter with passband response to filter the oversampled signal in the notch region; and a first modulator to translate the filtered signal to a higher frequency band than a frequency band of the notch region. Described is a method performed by a transmitter, the method comprising: oversampling a signal; and translating, in response to the oversampling, signal content in a notch region of a channel to a frequency band which is higher than a frequency band of the notch region.
Claims24
An apparatus comprising:
- a first sampler to oversample a signal, the signal to be processed for transmission through a channel having a notch region;
- a bandpass filter, with passband response, to filter the oversampled signal in the notch region;
- and
- a first modulator to translate the filtered signal to a higher frequency band than a frequency band of the notch region.
A method performed by a transmitter, the method comprising:
- oversampling a signal;
- and
- translating, in response to the oversampling, at least a portion of the oversampled signal content in a notch region of a wired channel to a frequency band which is higher than a frequency band of the notch region.
A system comprising:
- a channel having a notch region;
- a first Integrated Circuit (IC);
- and
- a second IC coupled to the first IC via the channel, the second IC including a transmitter which comprises:
- a first sampler to oversample a signal, the signal to be processed for transmission through the channel;
- a bandpass filter, with passband response, to filter the oversampled signal in the notch region of the channel;
- a first modulator to translate the filtered signal to a higher frequency band than a frequency band of the notch region;
- and
- a driver to transmit the translated filtered signal and the oversampled signal to the first IC.
An apparatus comprising:
- a filter to receive a signal on a first frequency band over a channel having a notch region, and to provide a filtered signal;
- and
- a modulator coupled to the filter, the modulator is to modulate the filtered signal to a second frequency band, where the second frequency band is lower in frequency than the first frequency band, and where the second frequency band is a frequency band of the notch region of the channel.
