Abstract: The method involves forming a partial signal (d) with a damped echo signal portion and an information signal portion, based on the signal. Another partial signal (c), substantially including only one echo signal portion, is formed based on the signal. The partial signal (d) is subtracted from the partial signal (c) in order to form an output signal (B) that includes only the information signal portion without the echo signal portion. Independent claims are also included for the following: (A) a device for suppressing an echo signal portion of a signal (B) a transmitter/receiver device.

Abstract: A driver circuit for driving a transmit signal for a line includes a signal amplifier configured to deliver a transmit signal, present at a signal input of the signal amplifier, amplified with a gain to a signal output, a line interface circuit connected between the signal output of the signal amplifier and the line, and a hybrid circuit connected to the line interface circuit, the hybrid circuit configured to suppress the transmit signal and couple a received signal received via the line to a signal input of the signal amplifier to provide impedance synthesis.

Abstract: The filter has a common-mode inductor (7) that receives transmitter signals from a class D line driver (1). A transformer arranged in the filter has primary windings (12A, 12B) that comprise connectors. A capacitor (16A) is interconnected between the connectors of the primary windings of the transformer and reference potential connectors (15A, 15B). An overvoltage protection unit is connected parallel to another capacitor (16B).

Abstract: The method involves determining a phase deviation between raising edges of signals (CLKA, CLKB), and determining a phase deviation between falling edges of pulse width modulated signals. A balance point phase deviation is determined based on the determined phase deviations between the raising and falling edges. The pulse width modulated signals have same rectangular waveforms.

Abstract: The method involves comparing input signals applied to a pulse width modulator with a threshold value. The synchronization loop is controlled, when the input signal exceeds the threshold value, in such a manner that changes of phasing of output signals of the pulse width modulator and/or a signal source is not caused by the synchronization loop for a certain time period. The signal source includes another pulse width modulator. Independent claims are also included for the following: (1) a device for controlling excessive load of a synchronization loop (2) a synchronization loop for synchronization of output signals of pulse width modulator with output signal of a signal source.
