Abstract
A microphone link system comprises a microphone that coverts an acoustic sound signal into an electrical sound signal, a slave unit that receives the electrical sound signal, a master unit, and a bus connecting the slave unit to the master unit. The slave unit comprises an analog-to-digital converter that converts the electrical sound signal into a digital sound signal; a signal processor that receives and processes the digital sound signal into a data signal; and a bus interface connected between the signal processor and the bus. The bus interface provides to the slave unit electrical power taken from the bus, sends the data signal to the master unit via the bus and receives from and sends to the master unit control signals via the bus.
