Return a sample time that results in successive samples 180 degrees out of phase with the AC power-line (mains) frequency.
Averaging an even number of samples recorded 180 degrees out of phase with the line rejects noise at the AC-line frequency.
The standard scripts use this function to control sample-timing in the initial-delay portion of the experiment. This improves the accuracy of Eoc measurements with high-impedance reference electrodes.
This function only works properly if LineFreq field in the GAMRY.INI file is set for the proper AC-line frequency.
REGULAR FUNCTION
NewTime = LineOpt(OldTime)
OldTime |
REAL |
The time calculated to result in successive samples that are out of phase with the AC power line. This time is as close as possible to OldTime. |
NewTime |
REAL |
The time used as the basis for the calculation. The calculated time is kept as close as possible to the OldTime. |
