摘要 |
<p>The duplex modulator has a modulator (4), a carrier signal generator (5), an amplifier stage and an antenna (7). An information signal source (1) is connected directly or indirectly with the modulator by another modulator (2). Another carrier signal generator (3) is arranged opposite to the former carrier signal generator of spectral low frequency. The latter modulator is actuated with a smaller modulation grade than the former modulator.</p> |
