Within the Chinese-developed HHT (Hilbert-Huang Transform) program, there exists a crucial function dedicated to computing instantaneous frequency and amplitude. This function performs signal decomposition and analysis, extracting time-varying frequency and amplitude characteristics from input signals. The implementation typically involves empirical mode decomposition (EMD) to generate intrinsic mode functions (IMFs), followed by Hilbert spectral analysis to derive instantaneous parameters. These extracted features enable identification of signal characteristics and support subsequent processing and analytical operations. As such, this function serves as a fundamental component in the HHT framework, representing an essential tool for advanced signal analysis applications. The algorithm effectively handles non-stationary and nonlinear signals through adaptive decomposition, making it particularly valuable for practical engineering implementations.
