Phase/Peak Selection

1. Automatic Phase/Peak Selection

In automatic peak selection the peak (Peak Amplitude) is defined as the maximum voltage value of a Phase (Peaks can lie at Sample Points only, NOT at intermediate positions between them). If there is more than one sample point of equal maximum value the mid-value is selected (or the value of equal maximum value to the left of the mid-value if there are an even-number of such values).

2. Manual Phase/Peak Selection

In manual peak selection the peak is selected by the position of the cursor and can be interpolated at positions intermediate between sample points (unlike in Automatic Phase/Peak Selection where peaks cannot lie at points intermediate between Sample Points). Interpolation of peaks in manual peak selection is undertaken using a Cubic Spline Interpolation algorithm.
