Computer simulation represents an extension of theoretical science; it can [be] and generally is based on mathematical models characterizing scientific theory, but it can be much more, because simulation can be used to explore the consequences of sit

Two assumptions underlie the Fourier transform process: stationarity and linearity. When signals deviate from these conditions, the transform outcomes are suspect. A chirp, which by definition has a frequency that varies with time, doesn't satisfy th

This fifth segment of six discusses filters. Filtering implies a frequency-dependent selection process, passing, for example, frequencies within a certain range and rejecting those outside that range. I describe some essentials for creating frequency

We consider two additional kinds of spectrum estimates: autoregressive (AR) estimates and the maximum entropy (ME) method. In the first approach, we assume that an AR process generates the time series, which means we can compute the PSD of the time s

When undergraduate students first compute a fast Fourief transform (FFT), their initial impression is often a bit misleading. The process all seems so simple and transparent: the software takes care of the computations, and it's easy to create the pl

Many students in physics and engineering courses often grapple with the mathematics they encounter and struggle to extract meaning from the analytic material they are learning, Much can be done computationally at this level to ask questions about and

In 1989, a decision was made that the journal Computers in Physics (CIP) would sponsor a software contest under the auspices of its education department. The goal was to reward software authors for their efforts to advance undergraduate pedagogy and

Empirical mode decomposition (EMD) associated with the Hilbert-Huang transform (HHT) deconstructs a time-series signal into a set of monocomponent signals called intrinsic mode functions (IMF). EMD also acts as a filter limiting the frequency range o

The conversion of time domain data via the fast Fourier (FFT) and Hilbert-Huang (HHT) transforms is compared. The FFT treats amplitude vs. time information globally as it transforms the data to an amplitude vs. frequency description. The HHT is not c
