Abstract
If the discrete Fourier transform of a step-like waveform is taken, a large truncation error results since only a finite number of samples is used. Several methods have been published to overcome this problem. The authors propose a novel method, based on Nicolson's method, to enhance resolution. This novel method is very powerful, particularly for time domain network analysis applications. The authors show the mathematical validity of the method developed. A practical demonstration is described in which the method is applied to an analytical truncated ramp and a measured waveform.
