Method and apparatus for receiving electromagnetic radiation within a frequency band |
摘要 |
A method and apparatus are provided for receiving electromagnetic radiation within a frequency band. The receiving is accomplished by intercepting electromagnetic radiation within the frequency band and converting the intercepted electromagnetic radiation into an electrical signal. Subsequently, a portion of the electrical signal is digitized into digitized signals. Each digitized signal represents the intercepted electromagnetic radiation within a portion of the frequency band. Finally, a composite digitized signal is generated from at least two of the digitized signals. Alternatively, the receiving process may be enhanced by intercepting first electromagnetic radiation within a portion of the frequency band and by intercepting second electromagnetic radiation within another portion of the frequency band. Subsequently, the first and the second electromagnetic radiation is combined into a composite electromagnetic radiation waveform. The composite electromagnetic radiation waveform is converted into an electrical signal which may be processed into digitized signals which form a composite digitized signal.
