Abstract :
An accurate generalized Fourier transform for almost-periodic signals is introduced. Verified by experiments, it is suitable for use in the accurate analysis of microwave nonlinear circuits driven by multitone signals. The least-squares orthogonal sampling algorithm is also very useful for solving common least-square fitting problems. Measured and simulated results for a MESFET amplifier show the significant improvement in accuracy
