1. A demultiplexing apparatus comprising:
- a signal receiver that receives signals;
an analog demultiplexer that analog-demultiplexes, in predetermined units of channels, the received signals received by the signal receiver and generates and outputs analog demultiplexed signals; and
a plurality of digital demultiplexers that digital-demultiplex, in units of sub-channels, the analog demultiplexed signals output from the analog demultiplexer and generate digital demultiplexed signals,wherein the analog demultiplexer allocates the analog demultiplexed signals to each of the plurality of digital demultiplexers based on an amount of bandwidth occupied by each respective one of the analog demultiplexed signals such that each of the plurality of digital demultiplexers receives an amount of signal-bearing bandwidth that is less than or equal to a threshold amount of bandwidth.

Abstract
A demultiplexing apparatus includes a signal receiving unit that receives signals, an analog demultiplexing unit that analog-demultiplexes, in predetermined units of channels, received signals received by the signal receiving unit and generates analog demultiplexed signals, and a plurality of digital demultiplexing units that digital-demultiplex the analog demultiplexed signals in units of sub-channels and generate digital demultiplexed signals. The analog demultiplexing unit controls, concerning the analog demultiplexed signals output to the digital demultiplexing units, a total value of bandwidths in which a signal is present so as to be a predetermined value or less.
