Double integral transforms for soft limiter modeling

The use of certain multidimensional transform techniques is useful in representing symmetric bandpass soft limiters whose transfer functions cannot be handled by the classical one-dimensional Fourier sine transform techniques of Rice, Bennett, and others. Limiter models analyzed are S(t))/(1+|S(t)|) and S(t)/(1+S²(t)^1/2, where S(t) is a narrowband bandpass AM/PM limiter input signal
