Filtering and spectral analysis of radio signals are used in various radio engineering
information systems for a wide range of applications, including the parallel real-time analysis
of large amounts of data. Along with devices for multi-channel radio signal filtering, both single
and multiprocessor spectral analysis devices can be used in these applications. Since these
spectrum analyzers subject the processed radio signals to the Fourier transform, we will call
them Fourier processors.
