Up-interface circuit e.g. for ISDN, uses discrete electronic components to amplify received signals via input buffer of digital integrated circuit |
摘要 |
<p>An Up-interface circuit has a reception part based on discrete electronic components and which amplifies the reception signals and enables these signals to be received by the input buffer of a purely digital integrated circuit. The external circuit consists specifically of at least one two-stage High-pass.</p> |
