Qualitative indices of broadcast transmitters in a single-sideband mode

D. A. Tkachenko

Abstract


It is suggested to characterize the quality of a signal at the output of high-frequency broadcast transmitters in a single-sideband mode with an attenuated carrier R3E by the same indices as are used in the usual amplitude modulation mode A3E. The indicated indices are calculated for a radio transmitter with separate amplification of the components of a single-sideband signal with consideration of the characteristics of the output filter of the switch anode modulator. The requirements imposed on the filter are formulated.
