Table 2.

Computational complexity based on execution time and memory allocation. The CPU clock speed during this process was 2.501 GHz. The execution time was measured with a precision of 1.00 × 10⁻⁷ s. The data for the peak/trough detection, feature extraction, and mathematical model are from a single sample file. These values are the same for both the training and test data. For ANN, the numbers correspond to a set of 30 measurements (our complete dataset).

	Total Execution Time (s)	Total Allocated Memory (Mbytes)
Peak/trough detection	183.72	941.66
Feature extraction	59.80	261.33
Mathematical model	218.30	2051.61
ANN training	509.31	8.48
ANN testing	11.65	4.63
