Full description
Diese App ermöglicht es, die Koeffizienten a(i) und b(i) frei vorzugeben und dann graphisch darzustellen. Gezeigt wird jeweils die Sprungantwort der Übertragungsfunktion des IIR-Filters 2. Ordnung. Damit lassen sich alle klassischen Übertragungsfunktionen darstellen. Der große Vorteil der App ist, sie können den Typ der Übertragungsfunktion vorwählen und dann eigene Änderungen der Parameter schnell und einfach testen. Das ist sicher einzigartig hier im Store.
