This is covered in detail in _Modern Spectrum Analyzer Theory and
Applications_ by Morris Engelson (Artech House, 1984).

Does Engelson's idea of "modern" include digitizing spectrum analyzers, which
have already taken over most of the mid- to high-end of test equipment and --
as with digital scopes -- will most likely soon be in all but the lowest of
the low-end of instruments?

Thanks,
