The development of the transistor has provided an active element having important advantages in space and power. As a result, the question arises whether strategic insertion of such active elements in passive networks might lead to interesting results. This paper describes a theoretical analysis, confirmed by experiment, of certain possible network applications of transistors. Four general areas are considered in which transistors are used as follows: to reduce the detrimental effects of…
