Time-Frequency-Energy Characteristics Analysis of Vibration Signals in Digital Electronic Detonators and Nonel Detonators Exploders Based on the HHT Method.

These IMF components can be extracted through EMD, where EMD decomposition concludes with the residual component obtained in the final decomposition stage, as indicated by the algorithm expression. (1) x ( t ) = ∑ j = 1 n c j ( t ) + r n ( t ) , In the equation, c 1 ( t ) , c 2 ( t ) , c 3 ( t ) , ..., c n ( t ) represent the components of the original signal in different frequency bands, collectively forming the original vibration signal, and their frequencies show a decreasing trend.
