给出了时频和时标方法的一般结果。对线性（短时傅里叶变换、小波变换）和双线性（维格纳 - 威利分布、仿射维格纳分布）方法都给予了关注，并强调了它们之间的关系。还考虑了所研究的方法与常数Q分析和模糊函数等方法之间的关系。
General results are presented for time-frequency and time-scale methods. Attention is given to both linear (short-time Fourier transform, wavelet transform) and bilinear (Wigner-Ville distribution, affine Wigner distribution) approaches, with emphasis put on their relationships. Also considered is the relationship of the methods examined to such approaches as constant-Q analysis and ambiguity functions.<<ETX>>
