专利摘要:
The invention relates to radio engineering. The purpose of the invention is to increase reliability. A single-band broadcasting transmitter contains analog-to-digital converter 1, single-band modulator 2, digital-to-analog converter 3, frequency converter 4, high-pass filter 5, high-frequency termination stage 6. Single-band modulator 2 produces a phase-free amplitude signal, which amplifies the signal in amplitude high-frequency terminal stage 6. This allows for increased reliability. 2 Il.
