An electronic circuit includes a transmitter with a first output configured to be connected to a first signal line of a signal bus, a second output configured to be connected to a second signal line of a signal bus, and an input configured to receive an input signal; and a ringing suppression circuit with a third output configured to be connected to the first signal line, and a fourth output configured to be connected to the second signal line. The transmitter is configured to operate in one of a first operating state or a second operating state dependent on the input signal. The ringing suppression circuit is configured to detect a change from the first operating state to the second operating state of the transmitter, and to operate in a ringing suppression mode for a predefined time period in response to detecting the change.
