Slicer and Acquisition
MLENGTH(2..0):
For noise suppression reasons a median filter has been introduced
after the actual data separation because of over sampling
successive samples could be averaged. Therefore an odd number
of sliced successive samples is taken and if the majority are ’1’ a ’1’
is sliced otherwise a ’0’. MLENGTH specifies how many samples
are taken. (Corresponds to slicer 1)
