1.7.8 PHASE LEAD/LAG Instruction (LLAG)
„ Outline
The LLAG instruction calculates the phase lead/lag according to the contents of a previously
set parameter table. The input (Input) to the LLAG operation must be integer or real number
data.
Double-length integer data cannot be used. The configurations of the parameter tables for
integer and real number data are different. Operations are performed by processing each
parameter as an integer consisting of the lower-place 16 bits.
