ABSTRACT:
This invention is a system that is capable of having a high dynamic range for the transmission of electrical information from an array of sensing devices to processing equipment via transmissions paths. A high gain quadrature multiplexer is coupled to the output of each pair of adjacent sensing devices and a low gain quadrature multiplexer is coupled to the output of each pair of adjacent sensing devices. The foregoing is arranged in such a manner that each sensing device is coupled to one channel of the multiplexer near it and to one channel of the adjacent multiplexer. A quadrature demultiplexer is coupled to the output of the high gain multiplexer and another quadrature demultiplexer is coupled to the output of the low gain multiplexer so that the faint signals received by the sensing devices will be passed to certain processing equipment through high gain channels and the loud signals detected by the sensing devices will be passed to processing equipment via low gain channels.
