EC_setNLPLevel
Description
Sets the required level of NLP.
Include
ec_api.h
Prototype
void EC_setsetNLPLevel(int* ptrStateX, int level);
Arguments
ptrStateX
level
Return Value
None.
Remarks
Each value represents a 6 dB change in the NLP level. Therefore, a value of 3
translates to an NLP level of 18 dB.
Code Example
EC_setNLPLevel(ecStateMemX, 3);
Sets the desired NLP level to 3 for the instance of the algorithm ecStateMemX.
Application Programming Interface (API)
a pointer to the state memory for this instance of AEC
an integer value between 0 and 15 representing the desired NLP
level
