Audio Sample

Russian AT-3104 Modem signal, 20-tone OFDMOrthogonal Frequency-Division Multiplexing DQPSKDifferential Quadrature Phase-Shift Keying signal. Has characteristic pilot tone located 3300 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). from suppressed carrier. All 20 channels operate at 75 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second..
