1. A method, comprising acts of:
- (A) providing a channelizer which receives a digital representation of an analog input signal and produces a plurality of digital output signals, each digital output signal representing a frequency band within a bandwidth of the analog input signal;
(B) during at least one first time period, demodulating at least one digital output signal produced by the channelizer to extract communications data from the at least one digital output signal; and
(C) during at least one second time period, processing at least one digital output signal produced by the channelizer for a purpose other than extracting communications data from the at least one digital output signal.

Abstract
A communications system comprising a channelized receiver is provided. In some embodiments, the system extends the capabilities of the channelized receiver, enabling the system to perform electronic surveillance monitoring (ESM) or relay functions. As such, the system may be employed to receive, process and provide information to downstream devices. In some embodiments, the system provides wideband communications capability. The system may also include a programmable demodulator for extracting communications data from incoming signals.

13. A communications system, comprising:
-
an analog-to-digital converter which receives an analog input signal and produces a digital representation of the analog input signal;
a channelizer which receives the digital representation of the analog input signal and produces a plurality of digital output signals, each digital output signal representing a frequency band within a bandwidth of the analog input signal; and
at least one circuit configured to demodulate, during at least one first time period, at least one digital output signal produced by the channelizer to extract communications data from the at least one digital output signal, and to process, during at least one second time period, at least one digital output signal produced by the channelizer for a purpose other than extracting communications data from the at least one digital output signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
