ABSTRACT:
An AM sterophonic broadcast signal for transmitting stereophonically related first and second audio information signals to at least one receiver comprises a first carrier component, a double-sideband component of a second carrier component being suppressed-carrier amplitude-modulated by the first audio information signal and a double-sideband component of a third carrier component being suppressed-carrier amplitude-modulated by the second audio information signal phase-shifted by 90 degree relative to the first audio information signal. The second and third carrier components have the same frequency as the first carrier component and their phases are advanced and retarded in phase by 45.degree. with respect to the first carrier component respectively. The AM stereophonic broadcast is compatible with an existing AM monophonic receiver. An AM stereophonic receiver compatible with an existing AM monophonic broadcast is also disclosed.
