Abstract
A two-wire communication system includes a first audio circuit, and a second audio circuit electrically connected to the first audio circuit via a two-wire bi-directional multi-node communication bus. The communication connects the first audio circuit to the second audio circuit wherein an audio signal, an enable signal, and a clip detect signal are transmitted over the bus.
Claims15
A two-wire communication system comprising:
- a first audio circuit;
- a second audio circuit electrically connected to the first audio circuit via a two-wire bi-directional multi-node communication bus, wherein the two-wire bi-directional multi-node communication bus connects the first audio circuit to the second audio circuit wherein an audio signal, an enable signal, and a clip detect signal are transmitted over the bus;
- a first two-wire communication circuit having an audio enable input, a clip detect output, and a first two-wire communication chip electrically connected to the bus, wherein the audio enable input and the clip detect output are electrically coupled to the first audio circuit;
- and
- a second two-wire communication circuit having an audio enable output, a clip detect input, and a second two-wire communication chip electrically connected to the first two-wire communication chip via the bus, wherein the audio enable output and the clip detect input are electrically coupled to the second audio circuit.
