de Vries, J.P. (author)In een intercontinentaal telefooncircuit ontstaan echo's door onjuiste afsluiting der tweedraads einden. Deze echo's hebben een lange looptijd. Om niet hinderlijk te zijn moeten zij sterk gedempt worden. Dit kan geschieden in het tweedraads einde door middel van een impedantietransparante versterker als echo onderdrukker. Dit type versterker...student report 1969
