Expressions for the output frequencies of nonlinear systems for general inputs are developed in signal processing fields. This can be regarded as a natural extension to the existing algorithm for nonlinear frequency ranges computation. The new result provides insight for the frequency domain analysis and design of nonlinear systems in more general situations.
