There are two implementations of the Welch() function, which causes confusion.

[ahn19]

The following error occurred while executing pyVHR_demo_deep.py.

"TypeError: Welch() takes 2 positional arguments but 5 were given"

This is the confusion caused by the implementation of two Welch() functions.
The Welch() function was implemented in BPM/utils.py and extraction/utils.py respectively, which caused confusion.
