FIELD: radio engineering.
SUBSTANCE: invention may be used for radio signals transmission by the help of single-band and other types of modulation, which is notable for simultaneous presence of amplitude and phase modulation. Single-band transmitter contains modulated single-band signal source, two pre-amplifiers, two video frequency amplifiers, two multipliers, two video frequency filters, two phase shifting units for π/2, medium frequency generator, two output cascades, adder unit and medium frequency generator.
EFFECT: significant decrease of out of band emission.
