1. A communication system comprising:
- a host unit comprising;
a first module having an oscillator configured to generate a master clock signal; and
a plurality of second modules coupled to the first module to receive the master clock signal, each of the plurality of second modules having a filter to filter the master clock signal, and a converter configured to use the filtered master clock signal in converting between analog and digital signals;
a transport mechanism; and
at least one remote unit distributed in a coverage area, the at least one remote unit communicatively coupled to the host unit via the transport mechanism, wherein the at least one remote unit comprises;
a third module having an oscillator configured to generate a master clock signal; and
a plurality of fourth modules coupled to the third module to receive the master clock signal, each of the plurality of fourth modules having a filter to filter the master clock signal, and a converter configured to use the filtered master clock signal in converting between analog and digital signals.
