STEREO MULTIPLEX OBJECTIVES
Stereo multiplex is the system whereby the left-and-right-channel signals of a stereo program are both sent out on one f.m. broadcast channel .In the method standardised by the Federal Communications Commission (FCC), the following objectives are attained:
- The left (L) and right (R) signals are sent, in separable form, within the 200 kHz FM broadcast channel bandwidth.
- Both signals are modulated onto the same carrier with negligible loss of signal-to-noise performance compared with that of monaural transmission. This is accomplished by means of the “interleaving” provided in the system.
- The system is compatible in that the owner of an f.m. receiver not equipped for stereo reception still receives an (L + R) signal ...
