Electronic circuit and method for recovering desired signals from carrier signals by demodulation as well as a modem

摘要: An electronic circuit comprising a rectifier which passes only one polarity of carrier signal; at least filter, subsequent to the rectifier, for suppression frequency range voltage matching network, is embodied so that it matches desired signal, and leads two inputs comparator, wherein an output comparator switched, depending on difference between inputs, feedback network connected in parallel with connects comprises high-pass characteristic. The invention furthermore method recovering signals from signal by demodulation modem.
