Abstract
Various techniques of active RC realisation of lowpass filters are discussed, and two methods which are considered to have engineering relevance are investigated in detail. The design of lowpass filters suitable for use in f.d.m. and p.c.m. systems is presented. The results of tests carried out on microelectronics models of these filters show that they meet the requirements for use in practical systems.
