Abstract
In Japan, there has been considerable activity in the research and manufacturing of quartz crystal filters, ceramic filters and mechanical filters. This paper reviews some of these contributions. An emphasis is placed on filters actually used. First multiple-mode resonators are reviewed; this concept having had profound effects on all types of filters. Quartz-crystal filters as well as other crystal filters are discussed. Then follow reviews on ceramic and mechanical filters.
