Ripple control transmitter.

摘要

An actual pilot frequency value (fL1) is formed in a central station (ZS) by a first pilot frequency generator (LG1), is transmitted by at least one transmission device (ÜS) and is supplied, in reproduced form (fL1R) to in each case one substation (US) having at least one ripple control transmitter (RS1, RS2). A second pilot frequency generator (LG2) is synchronised there by means of the reproduced value. This generator (LG2) generates the actual pilot frequency value again (fL2) such that it contains only phase and frequency deviations which can be compensated for within the limits of the control range (fmax, fmin) of the ripple control transmitter, by said transmitter, without phase discontinuities.
