Abstract.
It
is shown that if the quasiharmonious representation for a wave with the
limited slowly varying frequency exists, then it is unique. Necessary and
sufficient condition for the wave’s with slowly varying amplitude and frequency
existence is a slow varying parameters of the environment through the wave
propagates, and that the wave’s source is the oscillator with slowly varying
parameters.
Key words:
wave, quasiharmonious representation, slowly varying frequency, uniqueness.
