The 7th order splitter comprising, between line terminals (Line+, Line−) and POTS/ISDN terminals, the cascade connection of a LC filter cell (L21a, L12b, C21) and several elliptical filter cells (L22a, L22b, C22, C24, C25; L23a, L23b, C23, C26, C27). One or more of these filter cells is associated with a damped series resonance circuit comprising a capacitor (C21; C22; C23) series coupled with an RL circuit (R21, L24; R22, L25; R23, L26) between two winding (L21a, L21b; L22a, L22b; L23a, L23b) of a symmetrical coil of the associated filter cell. Each RL circuit is constituted by the parallel coupling of a resistor (R21; R22; R23) and a coil (L24; L25; L26)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Universal ISDN/POTS splitter","description":"A 7th order splitter for replacing the known 9th order splitter of an ISDN/POTS telecommunication system and reducing thereby the space occupied on the board as well as the cost.
