Abstract

PURPOSE:To obtain a stereophonic feeling in a FM broadcasting by transmitting monophonic sound signals after converting them to false extended sound image signals. CONSTITUTION:Main sound signal M consisting of monophonic sound signal 5 is generated, and an auxiliary sound modulation wave signal obtained by amplitude- modulating sub-carrier 10 in 9 by auxiliary sound signal S consisting of the sound signal, which is obtained by delaying signal 5 in 6 at a fixed time, is generated, and further, a pilot signal for demodulating the sub-carrier is generated in 12. Then, the composite signal where signal M, the auxiliary sound modulation wave signal and the pilot signal are synthesized in 8 is frequency-modulated in 3 and is transmitted.
