Remarks : If two amplitude values are entered for the same
frequency, a single vertical line is the result . In thi s
case, if an upper line is chosen, the amplitude of lesse r
frequency (amplitude 1) is tested . If a lower line is
chosen, the amplitude of greater frequency (amplitude
2) is tested.
For linear amplitude interpolation and linear frequency
interpolation, the interpolation is computed as:
