WinCD: Complex Demodulation Time-Series Analysis for Windows

This document describes WinCD, a program for extracting quantitative information about periodicity in time-series data using the method of Complex Demodulation (CD). The method is particularly well-suited for the analysis of variables that may produce changes in biological rhythms, such as sleep deprivation, adaptation to changes in work schedules, time-zone displacements, and various sorts of pathology (e.g., sleep disorders). WinCD enables exploratory analysis of time-series data by providing graphical displays of raw and processed time series, as well as numerous options for viewing and saving quantitative data. This document presents detailed descriptions of WinCD operations, examples of the use of the program, a discussion of CD theory and background, and a glossary of CD terms. The program and documentation are available for free distribution to interested parties.
