PT - JOURNAL ARTICLE AU - Standeisky, Istvan TI - An Am Stereo System with Additional Data Transmission DP - 1999 Dec 31 TA - Communications - Scientific Letters of the University of Zilina PG - 55--58 VI - 1 IP - 4 AID - 10.26552/com.C.1999.4.55-58 IS - 13354205 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.
