7964 (Contiguous) Series
Filter networks for suppressing an arbitrary number of contiguous
channels are supplied to order. For only a few channels, a series
connection of individual channel deletion filters is used. For a
large number of contiguous channels, a special network is used.
Its components consist of a “Brickwall” lowpass and highpass fil-
ter and a pair of specially designed bandsplitters. For an interme-
diate number of contiguous channels, two single channel deletion
filters establish the “Brickwall” ends while a less selective net-
work deletes the middle of the specified stopband.
