When calculating impulse, the first step is to break the signal into two signals which only contain positive or negative values.

Note that this script makes use of the Current_Signal function within Evaluate Expression. 


! Set all frames for all three components to DATA NOT FOUND for any frame
! 	ABOVE zero

/EXPRESSION= ( CURRENT_SIGNAL < 0 ) / ( CURRENT_SIGNAL < 0 ) * CURRENT_SIGNAL

;

! Set all frames for all three components to DATA NOT FOUND for any frame
