Lp('Expression','Omega')

Arguments

'Expression'	Signal or expression
'Omega'	2 Pi times the cut off frequency for the lowpass filter

Description

This function applies a very simple digital lowpass filter with a limit frequency 'Omega'/(2*Pi). When applied to a signal 'Expression', the function returns a signal where the frequencies above the limit frequency are attenuated.

Note that due to the simple algorithm the attenuation is rather small and it is recommended to use the filter designer if specific filters are required.
