Present order tracking methods for solving noise and vibration problems are reviewed, both FFT and resampling based order tracking methods. The time variant discrete Fourier transform (TVDFT) is ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

This is a preview. Log in through your library . Abstract A classification of methods for generating discrete Fourier transform pairs is given, followed by a table of 29 pairs. Many of these are new, ...

Design linear discrete-time systems and filters and analyze their behavior. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of ...
