FIELD: methods and devices for processing composite audio broadcast signal. ^ SUBSTANCE: proposed method includes following procedures: analog-modulated part of audio broadcast signal is separated from digital-modulated part of audio broadcast signal; data from analog component of broadcast signal is separated from its digital component to produce mixed output audio signal. Method is also proposed for transferring composite audio broadcast signal that has analog part and digital part to suppress irregular interruptions in reception of mentioned audio broadcast signal by adding modem frames with analog part of broadcast signal which incorporate audio frames presenting digital part of audio broadcast signal. ^ EFFECT: provision for suppressing irregular interruptions in reception of audio broadcast signal. ^ 25 cl, 4 dwg |
