An example controller for a switched mode power supply includes a zero-crossing detector, drive logic, and an on-time extension block. The zero-crossing detector is coupled to generate a first signal prior to a zero-crossing of an input voltage of the power supply. The drive logic is to generate a drive logic output signal in response to a feedback signal, where the drive logic output signal is representative of an initial on-time. The on-time extension block is coupled to the zero-crossing detector and to the drive logic to generate a drive signal in response to the drive logic output signal. The drive signal controls switching of a switch to remove charge from a filter capacitor of the power supply. The drive signal is representative of a total on-time of the switch equal to a sum of the initial on-time and an extended on-time, where the extended on-time is responsive to the first signal.

A device for predistorting a transmission signal to be transmitted over a nonlinear transmission path comprises an estimator for determining an error signal depending on the transmission signal and a previously registered transfer characteristic of the nonlinear transmission path. The error signal represents an estimate of an error generated due to the nonlinearity of the trans-mission path.
