Wenn ich beispielsweise auf einen Träger mehrere Schwingungen draufklatsche und diese nun auf der anderen Seite empfangen will, wie entscheide ich genau, welches Signal der auf dem Träger ist empfangen wird? Hat man dafür einen Tiefpassfilter der mit einer Abstimmdiode oder veränderbaren Kapazität die Grenzfrequenz variiert? Vielen Dank im Voraus!
