<p>The modulator system consists of a pair of two-phase modulators, each of which has a terminal for an oscillator control signal. It is used for the base band signal and for the modulated R.F. signal for use in time division multiplex systems. At least one negative feed-back circuit (A, pi, delta phi, B) is the h.f. signal (RF) compensating the residual control voltage (U TR) of the control signal (LO) in the R.F. signal circuit.</p> |
