Release Feature and bugfix release "FFT Window" · chipmuenk/pyfda

New Features

display pop-up window for showing time and frequency properties of FFT windows for filter design and spectral analysis of transient signals.
improve parameter entry and tooltipps for windowed FIR filter design
add more windows and use same widget for filter design and spectral analysis
new stimuli AM, FM, PM for transient response
first successful generation of a binary for Windows using pyinstall. "spec" - files are included for own experiments

improve robustness when importing csv Files (still room for improvements)
suppress "divide by zero in log10" warnings
reduce number of debug logging messages, especially from matplotlib
eliminate false logging warnings and errors
refactor common libraries, all libraries now are within the folder "libs"
simplify clipboard instantiation
improve robustness by enforcing inputs <> 0 ('poszero', 'negzero') in input fields
rename pole/residue export format suffix to *.txt_rpk

only install PyQt5 when it cannot be imported to prevent double installation under conda.
don't try to import PyQt4 (pyfda isn't compatible anymore) as this gives strange error messages on some systems
stop installation when matplotlib version 3.1.0 is detected as it isn't compatible
fix crash with matplotlib version 3.2.1 due resulting from changed colormap list
fix crash when selecting Fixponpoint Tab for a filter design without fixpoint widget
fix error when trying to load *.npz files: numpy.load() requires allow_pickle = True since version 1.16.3 for security reasons
fix error when trying to load pickled files
[ ERROR] [pyfda.input_widgets.input_files:187] Unexpected error: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
fixed buggy export of coefficients in Xilinx and Microsemi format
Changing the CSV option box parameters from 'file' to 'clipboard' or the other way round in input_coeffs or input_pz would not update the other tab
