FIELD: physics.
SUBSTANCE: single sideband (SSB) transceiver contains a transmitting device containing a phase shifter for the phase shift of the input acoustic signal; the input acoustic signal includes phase-shifted signals used for the signal modulation for transmission; the device transmits a frequency shift keyed (FSK) signal with a single sideband (SSB) corresponding to the input acoustic signal; the FSK signal of the SSB contains analogue information; a receiving device capable of generating the upper and lower sidebands, and a connection control device containing a microcontroller, which automatically selects one of the upper and lower sidebands depending on interference detected during transmission or reception.
EFFECT: development of inexpensive transceiver and automatic selection of channel without interference.
