Enumeration Type Documentation

enum typeIntegrationMethod

Enumeration type that specifies how to calculate the integral to obtain the value of the pdf at a given value of the current from the characteristic function

Automatically set by code.

Possible values:

• FOURIER_TRANSFORM = 1 For now we don't seem to need this option So not implemented yet
• STEEPEST_DESCENT = 2

Enumerator:

FOURIER_TRANSFORM
STEEPEST_DESCENT

enum typeOutput

Enumeration type that specifies sort of statistics of electrical pdf to be generated by the class

Possible values:

• PDFS = 1, i.e., pdfs in each bit at clock recovery together with average pdfs of marks and spaces
• EYE = 2, i.e., a contour eye diagram

Enumerator:

PDFS
EYE
