Classification: CPC G  H | IPC H

Claim 0:
1. A multiplexing input circuit, comprising:
a plurality of separate channel circuits having inputs operatively coupled to respective antennas;
a multiplexing circuit operatively coupled to outputs of the channel circuits for time division multiplexing the channel circuit outputs and providing multiplexed output signals;
one or more connected amplifiers, with at least one connected amplifier operatively coupled to an output of the multiplexing circuit;
one or more analog-to-digital converters operatively coupled to outputs of the one or more connected amplifiers, wherein the total number of analog-to digital converters is smaller than the number of channel circuits and antennas;
a digital signal processing circuit operatively coupled to outputs of the one or more analog-to-digital converters to process the analog to digital converter outputs to determine information associated with the antenna output; and
a switching mechanism;
wherein one of the plurality of channel circuits is configured to be put into an open state at a time allowing an output signal to bypass the switching mechanism.
