| 1. A circuit comprising:
a differential signal splitting mechanism configured to (i) receive a first differential signal as an input, (ii) amplify
the received first differential signal, (iii) produce from the amplified first differential signal a number of second differential
signals, each being substantially identical to the amplified first differential signal, and (iv) output each of the amplified
second differential signals; and
a number of tuners corresponding to the number of second differential signals, each tuner being configured to receive one
of the second differential signals output from the differential signal splitting mechanism and derive one or more informational
differential signals therefrom.
