Method and apparatus for transmitting and receiving amplitude modulated stereo

摘要: The transmission of amplitude modulated stereo is achieved by modulating the positive and negative half cycles a radio frequency carrier separately with different one channels carrying audio intelligence program, thereby transmitting both on same carrier. modulation done after final amplification signal, directly in antenna circuit, order to eliminate mixing two channels, utilizing each cycle current activate separate modulators connected sources signals. Reception this inserting diode resonant circuit receiving antennas opposite directions, whereby responsive only channels.
