| 摘要 |
An electronic arrangement for generating an amplitude and phase-modulated carrier signal having a phase modulation stage with two inputs for receiving two modulation signals, which modulation stage generates two different phase-modulated signals having the same carrier frequency and substantially the same amplitude, and an output stage to which the phase-modulated signals are applied for assembling by means of summation of the phase-modulated signals to produce the amplitude and phase-modulated carrier, the amplitude of which is modulated in dependence on the phase difference of the phase-modulated signals and the phase of which is modulated in dependence on the sum of the phases of the phase-modulated signals.
