Frequency Domain

A robust function that uses frequency-domain -i/frequency filtering to integrate a function. Edge-tapering is used to minimize aliasing errors.

RF Blockset converts frequency domain RF information to a baseband-complex time-domain model, for fast execution and compatibility with Simulink signal processing and communications blocks.This simple model illustrates some relationships inherent in the conversion...* Length of impulse response =...

Reference - This code is based on the technique described in: D.G. Bailey - Detecting regular patterns using frequency domain self-filtering, 1997 Intl. Conf. on Image Processing, 1:440-3.

This GUI can be used to analze control systems in time domain, in frequency domain and using using state space analysis techniques. It also provides an additonal feature of designing a second order system in state space design using pole placement approach.


Platforms: Matlab

It creates blocks of surrogate data with the same second order properties as the original time series dataset by transforming the original data into the frequency domain, randomizing the phases simultaneously across the time series and converting the data back into the time domain.
