Abstract

Embodiments of a method for processing a baseband signal in a Direct Current (DC)-suppressed system, a system for processing a baseband signal in a DC-suppressed system, and a smart card are described. In one embodiment, a method for processing a baseband signal in a DC-suppressed system involves processing the baseband signal in the analog domain with a first high pass filter (HPF), converting the processed baseband signal to a digital signal, and processing the digital signal in the digital domain with a second HPF to provide a discrete-time differentiation of the baseband signal. Other embodiments are also described.
