US Patent 7408337 Compensating for loss in a transmission path

An apparatus to compensate for loss in a transmission path includes a circuit block that incorporates time constants into a signal transmitted via the transmission path. The time constants counteract at least part of inherent time constants that contribute to loss in the transmission path. The circuit block includes a resistive circuit and a capacitive circuit. The capacitive circuit and the resistive circuit together contribute to the time constants. The capacitive circuit includes plural capacitors that are each switchable via the circuit block. An amount of compensation provided by the apparatus corresponds, at least in part, to the loss in the transmission path.
