AMPLITUDE-MODULATED TRANSMITTER WITH CONTROLLED CARRIER VALUE |
摘要 |
<p>An amplitude-modulated transmitter wherein the carrier value (T) is controlled in accordance with an improved HAPUG (controlled-carrier) method. Increased energy saving with simultaneous increase of the signal-to-noise ratio at the reception site is achieved by controlling the carrier along a static characteristic (SK) which begins, with a decreasing modulation level (P), with a residual carrier value (R), drops with increasing modulation levels to a minimum carrier value (Tmin) and passes into an ideal carrier-control characteristic only above a first level value (P1). Additional dynamic control results in a reduction in cross-over distortions.</p> |
