These predefined filters are designed for the special spectrum characteristics of the dif-
ferent communication standards. However, depending on the selected filter form one
or more filter parameters are additionally provided for even precise adjustment of the
filter characteristic, like more steeper edges or customization the transition bandwidth.
For more information on the provided settings, refer to "Impact of the Filter Parame-
ters" on page 348.
Impact of the Filter Parameters
The following is a simple description of the filter parameters and the way they affect the
main filter characteristics. Changing filter parameters is an effective way to ensure that
the entire bandwidth of the desired signal is allowed to pass and adjust the filter form to
reach the spectrum mask requirements
