Abstract
THE study of impedance networks has acquired much importance during the past decade, as a result very largely of the pioneer work of G. A. Campbell on wave-filters. The literature of the subject has hitherto been scattered through the pages of patent specifications and technical journals, particularly the Bell System technical journal; the present very thorough account, which is particularly complete in its treatment of wave filters, will therefore be of the highest value to electricians. Although wave-filters have hitherto been used mainly in their practical applications to telephony, telegraphy, and wireless transmission, the precision with which they can be made to suppress some frequency bands while admitting others may render them of service in some branches of pure research.
