Noise suppressor

A noise suppressor, comprising:

• a first differential-mode transmission module including a pair of first terminals, a pair of second terminals, and a third terminal;
• a second differential-mode transmission module including a pair of first terminals that are respectively and electrically connected to said second terminals of said first differential-mode transmission module, a pair of second terminals, and a third terminal, the pair of first terminals of said second differential-mode transmission module being electrically connected to the pair of second terminals of said first differential-mode transmission module respectively;
• and
• a common-mode absorption module including a first terminal that is electrically connected to said third terminal of said first differential-mode transmission module, a second terminal that is electrically connected to said third terminal of said second differential-mode transmission module, and a third terminal that is electrically connected to a reference node;
• said first and second differential-mode transmission modules being configured to receive a differential signal at said first terminals of said first differential-mode transmission module, and to permit the differential signal to be transmitted through said first and second differential-mode transmission modules to be outputted at said second terminals of said second differential-mode transmission module;
• said common-mode absorption module being configured to absorb common-mode noise of the differential signal from at least one of said first differential-mode transmission module or said second differential-mode transmission module.
