Abstract :
Presents a bipolar monolithic version, for frequency division telephone multiplex equipment, that has a marked improvement in performance compared with discrete component versions. The principles of operation and the design criteria and limits are discussed in full detail, particularly with respect to CCITT recommendations. Special attention is devoted to the analysis of the circuit and technological solutions that have been implemented to achieve an overall operation accuracy of 0.2 dB together with a high level of reliability.
