Expose ifilter, perfosr, and ntfperf wrappers aligned with MATLAB names. Harden extract_freq_components validation, extend OSR sweep options, and document parity in API docs and python_matlab_parity.rst. Co-authored-by: Cursor <cursoragent@cursor.com>
Add Python 10_oversampling example scripts (noise shaping, ifilter, ntfperf/perfosr), extend ADC_Signal_Generator noise shaping, add MATLAB noiseshape.m with tests, and wire examples into docs and skill maps. Co-authored-by: Cursor <cursoragent@cursor.com>
