Patent ID: 6961385

Claim:
A signal processing system comprising: a modulation circuit to alternately pass-through and cross-over a differential input signal in accordance with pass-through control signal φ chA and cross-over control signal φ chB ; and a demodulation circuit coupled to the modulation circuit to alternately pass-through and cross-over the differential input signal modulated by the modulation circuit in accordance with pass-through control signal φ chC and cross-over control signal φ chD , wherein control signals φ chA and φ chC are nonoverlapping with respect to control signals φ chB and φ chD , control signal φ chA is configured to delay ceasing pass-through of the differential input signal with respect to ceasing pass-through of the differential input signal in accordance with control signal φ chC , and control signal φ chB is configured to delay ceasing cross-over of the differential input signal prior with respect to ceasing cross-over of the differential input signal in accordance with control signal φ chD .
