RT Journal Article SR Electronic A1 Standeisky, Istvan T1 An Am Stereo System with Additional Data Transmission JF Communications - Scientific Letters of the University of Zilina YR 1999 VO 1 IS 4 SP 55 OP 58 DO 10.26552/com.C.1999.4.55-58 UL https://komunikacie.uniza.sk/artkey/csl-199904-0007.php AB Previously proposed systems for AM stereo are discussed. The new compatible AM stereo system is described. The new system makes it possible to implement a stereo transmission with a bandwidth in the sound channels from 50 Hz to 4.5 (or more) kHz and a data transmission with a modulation rate of 25 bit/sec.
