Function Description

This module implements the following functions:

• Basic vector operations: logical shift operation, vector conversion, vector statistics, sampling function, and initialization function
• Signal conversion: FFT, CZT, power spectrum, and Hilbert transform
• Filtering: convolution, FIR filtering, resampling, median filtering, and autocorrelation
• Window functions: Blackman, Hann, Kaiser, Hamming, and Bartlett
• Mathematical operations: arithmetic operation, triangle operation, and power, root, and exponential operations
