A transmitter and a receiver

Abstract

The subject-matter of the present disclosure provides a transmitter for a master clock of an audio system. The transmitter comprises an input configured to receive a message to be sent to a receiver of an audio device of the audio system and clock frequency information of a clock signal for synchronising the audio device; a data stream generator configured to determine a data stream based on the message; a pulse shaper configured to generate an encoded clock signal in the form of a rectangular wave having an initiating edge timing based on the clock frequency and a terminating edge timing being earlier than or later than a half cycle of the encoded clock signal depending on a bit value of the data stream; and an output configured to transmit the encoded clock signal to the receiver.

Dependencies are inferred from the claim text.
