= Bilinear time–frequency distribution
{wiki=Bilinear_time–frequency_distribution}
The bilinear time-frequency distribution (TFD) is a type of representation used in signal processing to analyze signals in both the time and frequency domains simultaneously. It is particularly useful for non-stationary signals, where frequency content changes over time. The bilinear time-frequency distribution allows for a clearer understanding of how the spectral content of a signal evolves. \#\#\# Key Characteristics 1. **Bilinear Nature**: The term "bilinear" refers to the way in which the distribution is calculated.
