For z(t) = ␦(t), the bilinear representation P f (x, u; w, z) = |S f (x, u; w)|2 is known as the spectrogram: the squared modulus of the windowed Fourier transform. 87). 5 Spectrogram of a sinusoidal FM signal exp{i[2u0 x + a 1 sin(2u1 x)]} with (a ) a medium-sized window, leading to a space-frequency representation with smearing, and (b) a long window, leading to a pure frequency representation. the spectrogram. Although the spectrogram is a quadratic signal representation |S f (x, u; w)|2 , the squaring is introduced only in the final step and therefore does not lead to undesirable cross-terms that are present in other bilinear signal representations.
