Combined Magnitude Phase Spectrogram Signal Processing

The patent segments the spectral information into two distinct components: magnitude spectrogram and phase spectrogram. By separating these components, the system can process and preserve phase information independently while maintaining the visual interpretability of magnitude information. The phase spectrogram is generated separately and then combined with the magnitude spectrogram to reconstruct the full signal representation.

The patent adds a new dimension to the traditional spectrogram by incorporating phase information as a separate channel or layer. Instead of discarding phase data, the system creates a multi-dimensional representation where both magnitude and phase coexist, enabling neural networks to utilize phase information for improved signal analysis while maintaining compatibility with standard visualization techniques.

The patent employs dynamic time-windowing strategies where the window size and overlap parameters can be adjusted based on the specific analysis requirements. By making the transform parameters adaptive rather than fixed, the system can optimize the balance between frequency and time resolution for different signal characteristics and analysis goals, allowing high frequency resolution when needed while maintaining acceptable time resolution.

The system allows dynamic adjustment of key parameters including window size, hop length, and transform length. These parameter changes enable the spectrogram generation to adapt to different resolution requirements, permitting high frequency resolution for stationary signals while using shorter windows for transient analysis, thus overcoming the fixed resolution limitation of conventional STFT.
