FIELD: generation of analog and digital signals for.
SUBSTANCE: method for generating signal of weakened amplitude for simultaneous transfer, meant for simultaneous transfer of digital radio broadcast and analog radio broadcast signal, contains stages of generation of primary error signal, generation on basis of primary weakened signals of final signal for simultaneous transmission. Generator of weakened amplitude signal for simultaneous transmission, meant for simultaneous transfer of digital and analog radio broadcast signals contains final signal generator for simultaneous transmission, advance weakening cascade, containing primary signal generator for simultaneous transfer, meant for generation, on basis of aforementioned digital and analog broadcast signals, of primary error signal and primary amplitude weakening block, meant for weakening of at least one of aforementioned radio broadcast signals.
EFFECT: generation of stable signal for simultaneous transfer with maximal level of signal for analog and digital transferred signals, allowing to increase primary service area for analog and digital system.
