Abstract
A system is operated to transmit signals from a transmitter to a receiver. The transmitter is muted. A receiver transfer function for the receiver is adjusted so that an output signal of the receiver is minimized. A transmitter transfer function of the transmitter is set to be inverse to the adjusted receiver transfer function.
Claims10
A method of operating a system for transmitting differential signals from a transmitter to a receiver that produces an output signal by comparing the differential signals, the method comprising:
- muting the transmitter by placing the transmitter in an operation state in which the transmitter is silent;
- determining a receiver transfer function by adjusting a gain value and/or a phase value of an input stage of the receiver so that the measured output signal is a minimum;
- setting a transmitter transfer function of the transmitter to be inverse to the determined receiver transfer function to suppress common mode interference.
A method of operating a system for transmitting signals from a transmitter to a receiver, the method comprising the steps of:
- muting the transmitter;
- adjusting a receiver transfer function of the receiver so that an output signal of the receiver is minimized by adjusting a plurality of stages of the receiver;
- and
- setting a transmitter transfer function of the transmitter to be inverse to the adjusted receiver transfer function by adjusting the plurality of stages of the transmitter to be inverse to a respective one of the plurality of stages of the receiver.
A transmitter for a system for transmitting signals from the transmitter to a receiver, the transmitter comprising
- a muting unit adapted for muting the transmitter by placing the transmitter in an operation state in which the transmitter is silent;
- and
- a setting unit adapted for setting a transmitter transfer function of the transmitter to be inverse to a receiver transfer function of the receiver that is determined by adjusting a gain value and/or a phase value of an input stage of the receiver so that a measured output signal of the receiver is minimized.
A receiver for a system for transmitting signals from a transmitter to the receiver that produces an output signal representing the transmitted signals from the transmitter, the receiver comprising
- an adjustment unit for determining a receiver transfer function by adjusting the receiver, in response to a mute state of the transmitter, so that the measured output signal of the receiver is minimized;
- and
- a transfer unit for transferring the determined receiver transfer function to the transmitter to enable the transmitter to set a transmitter transfer function of the transmitter to be inverse to the determined receiver transfer function.
