inversionsphänomen - unterdrückungsschaltung

摘要

an fm signal (102), which has no nulldurchgangspunkte becomes a eingangsanschluu00df (120) of a inversionsphu00e4nomen - unterdru00fcckungsschaltung transferred.with this eingangsanschluu00df (120), a second polaritu00e4tsdiskriminatoreinrichtung (117) and a body (111) for suppression of the lower seitenbandes, with this body (111), a first polaritu00e4tsdiskriminatoreinrichtung (112).a pulsextrahiereinrichtung (119) receives output signals of the first polaritu00e4tsdiskriminatoreinrichtung (112) and the second polaritu00e4tsdiskriminatoreinrichtung (117) for production of pulses (106) in the areas of fm signal (102), in which a nulldurchgangspunkte existing n.the thus obtained pulse (106) is then in a waveform structure (110) with the fm signal (102) of eingangsanschluu00df (120) combined. in this way, an fm signal (107) to generate, in which the nulldurchgangspunkte again are available.
