Abstract :
The high-speed transmission of data over voice frequency telephone links creates the need for variable group-delay equalization networks. This paper describes two alternative group-delay sections, the characteristics of which may be continuously adjusted over the approximate bandwidth (300 to 3000 Hz). Both of the proposed networks provide for the desired degree of group-delay adjustment using only two resistive controls neither of which demand high precision components.
