Member Function Documentation

◆ generateRandomDigits()

int DigitGenerator::generateRandomDigits ( float  occupancy,
std::vector< Digit > &  digits 
)
inline

Populate the digits vector with (Nmch * occupancy) digits where Nmch is the total number of channels in MCH (1064008)

Each member variable of the digit is uniformly distributed within its expected range, as an attempt to maximize the entropy of the generated digits, which can be handy to test the efficiency of the entropy encoder used to create the Compressed Time Frame (CTF) for instance.

Parameters
occupancyis a number between 0 and 1. @digits a vector where the generated digits will be appended. That vector is not cleared by this function, so digits can be accumulated if need be.
Returns
the number of digits added to the input digits vector.
