Full Changelog: v2.0.0...v2.1.0

v2.0.0

Code refactoring:

• The core modules have been rewritten (other modules will also be rewritten and new ones added);
• Added doxygen comments;
• Updated cmake lists;
• Updated readme.

There are modules now (see readme for description):

• TCore - Contains SignalProcesserException class.
• TSignalLine - Represents a signal line composed of points with various configurable parameters. TSignalLine is responsible for managing a signal line by allocating memory for points and adjusting signal parameters. It provides methods to set and retrieve points and to validate the correctness of the signal's parameters.
• TGenerator - Generating a signal line with specified parameters. Allows for the generation of a signal line based on configurable parameters. It provides methods to retrieve the generated signal and its parameters.
• TFileWriter - Responsible for writing a signal line to a file. Allows saving a signal line to a file at a specified location. It uses the signal line and file path provided either directly or through parameters.
• TGnuPlotViewer - Responsible for visualizing a signal using GnuPlot. Allows plotting a signal stored in a file using the GnuPlot tool. It is configurable through a set of parameters including the file path, GnuPlot path, and axis labels.

Full Changelog: v1.2.1...v2.0.0

v1.2.1

Added to core:

• Added TMultiplier - multiply tow "similar" waves (using only points of the original waves)
• Added TDerivative - returns a derivative wave (has points count less by 1 from original wave) (using only points of the original wave)
• Added TIntegral - returns an integral wave (has points count less by 1 from original wave) (using only points of the original wave)
• Added TAmplitudeDetector - detects amplitude of a sinus wave with noizes (using only time, samping frequency and points themselfes of a signal)
• Added TCorrelator - detects if two waves are similar in sine frequency and returns amplitude of this as a factor of similarity (using only time, samping frequency and points themselfes of a signal)
• Added TFourierTransform - returns fourier wave (graph where axis x is frequency; y - amplitude) (using only time, samping frequency and points themselfes of a signal)

Other

• Fixes in TSignalWave

Full Changelog: v1.1.0...v1.2.1

v1.1.0

Added new element.

Added to core:

• TSummator - signal summator

Other

• Some fixes

Full Changelog: v1.0.0...v1.1.0

v1.0.0

Added basic functionality.

Added to "core":

• TGenerator - generates a sine wave
• TGenerator: added addNoise - adds noise to a wave (not a "true" noise right now)
• TSignalLine - a sine wave class with methods and struct to base work with (set(...), add(...), etc.)

Added to "io":

• TFileWriter - writes a sine wave x and y coordinates to a file
