Feeding circuit arrangement for digital telecommunication terminals. |
摘要 |
<p>A circuit arrangement for feeding digital telecommunication terminals via a transformerless physical two-wire interface, proposes a real choke or resistance feed instead of the previously used phantom circuits. The DC-isolation and the signal input and output are provided by capacitors. Level matching is performed either by appropriate dimensioning of the chokes and resistors or by suitable level matching circuits. <IMAGE></p> |
