Выравнивание группового времени задержки может производиться двумя способами секция полоскового выравнивателя можч объединиться с фильтром или выравниватель может присоединяться к фильтру каскадно с помощью подпрограммы DEELAY Выравниватели также могут выполняться на элементах как с сосредоточенными, так и с распределенными параметрами

Наряду с пассивными цепями программа FILSYN может сннте,*ировать цифровые н активные фильтры Для иллюстрации возможности применения про граммы FJLSYN при проектировании фильтров приведем пример синтеза фильтра нижннх частот 5-гигагерцевого диапазона, состоящего из двух единичных элементов и трех параллетьных разомкнутых шлейфов Результаты выполнения программы FILSYN приведены на рис 20.11 а соответствующие характеристики фнльтра представлены на рис 20,12
