Member Function Documentation

◆ backup()

void backup ( )

inline

Pushes a backup of transfer function states into the backup buffer.

Note: Only the delayed states are backed up, not the current value or the coefficients

void restoreBackup ( size_t nSteps = 1 )

inline

Restore the backup at the given step.

Parameters

[in] nSteps The number of steps backwards in time to restore (1=last step) must be >=1

void setBackupLength ( int nSteps )

inline

Setup the number of backup steps to remember (size of the backup buffer)

Parameters

[in] nSteps The number of steps to remember

double updateWithBackup ( double u )

inline

Make a backup of states and then calls update.

Parameters

[in] u The new input value
