Kaiser

This key applies the Kaiser windowing function to the selected filter.

Windowing improves out of band performance (ACP) by smoothing the

filter’s transition to zero, but simultaneously degrades passband

performance (EVM).

Selecting the

Kaiser softkey activates the Beta factor that can be

adjusted for trade-off between optimized ACP and EVM. Decreasing the

Beta factor value improves EVM; increasing the value improves ACP.
