"MK111220001.mat" contains 100 sweeps, divided into 4x5=20 classes.
Three sweeps have been excluded: Sweep no. 5 (class 1.3), 69 (3.3) and 87 (0.1). Leaving 97 sweeps included.
Classification acts on analog output (both dimensions): Sub classes differ in amplitude, main classes in cycle time of a haver sine. The analog output is sampled on analog input channel 0; pre-processing applies a 1st order 20Hz low-pass filter.
Y-analysis measures the maximum of the pre-processed signal between 5 and 65ms
