Guidelines for Generations Derivative Spectra

In conclusion, the most important points to remember for generating derivative spectra are summarized here in the form of twelve guidelines. Obey these instructions strictly if you want to avoid mistakes. 

Start the derivative operation by filtering or smoothing the rough data of the fundamental signals. Carry these operations out only as far as is absolutely necessary. 

Filtering or smoothing always involves a compromise between resolution, noise (SNR), and distortion of the signal. 

If it is practicable in some way, accumulate signals many times. This is the best method of smoothing without deforming the shape of the signals. 

Smoothing by a sliding window is more effective if you take a few data points several times rather than many points only once.
