Solutions of Inorganic or Organic Substances

In the process of studying higher-order derivatives, four substances proved especially suitable for testing the quality of derivative devices. 

The spectrum of this substance has the shape of an asymmetric Gaussian curve. Only efficient derivative modules are able to resolve the signal in d into two main peaks (Fig. 4-4). 

This is a good example of a Gaussian curve superposed by an underlying exponential function, which is eliminated by higher-order differentiation (Fig. 4-5). 

In this case, the resolving of a shoulder on the side of a peak can be demonstrated (Fig. 4-6). 

The derivative spectra of this protein (extracted from bovine pancreas) show the resolution of small irregularities on the flanks of the fundamental spectrum (Fig. 4-7) compare also the RNase spectra in [2], generated by analog differentiation.
