The design parameters specified for FIR filters are different from those used for Infinite Impulse Response (IIR) filters such as Butterworth filters. Digital FIR phase filters are recommended for processing EMG signal amplitude. not a function of frequency, and so they can also be used online in real-time. Unlike Butterworth filters, these filters are “linear-phase”, which means the delay introduced by the filter is a constant (actually 0 in LabChart), i.e. These FIR filters are designed using the “Window Method” with a Kaiser window with beta = 6, which results in pass and stop band ripple of less than 0.5%. The standard digital filters supplied by the LabChart Digital Filter Channel Calculation are zero-phase-lag Finite Impulse Response (FIR) filters. A Butterworth filter is recommended for general sEMG signal filtering use - it is frequency-based and has a faster setting time in response to signal transients, and the effect of filtering can be easily understood and predicted. The simplest and most direct means of increasing the fidelity of the sEMG signal is to filter the maximum amount of noise while retaining as much of the desired EMG signal frequency spectrum as possible. However, it improves the way users can exchange the files and makes available an easy way to load up this type of content.The surface electromyographic (sEMG) signal that originates in the muscle is contaminated by various noise signals or artifacts. LabChart Reader is a simplified version of the full-blown application that can record and save data. Thanks to its versatility, the application includes the possibility to view the data in multiple ways these include Zoom view (check selections in detail) Scope view (includes analysis abilities of a digital storage oscilloscope) and Chart view (default method). Opening multiple files at the same time can be easily done and it comes in handy especially if the user wants to compare various data. Work with several files and change the viewing method The application window is simple and offers multiple layout choices for a better view of the information. Moreover, it allows making calculations and analyzing the content.Īmong the supported formats there are audio files (WAV, FLAC, OGG), AcqKnowledge items, WinDAQ, Axon PCLAMP and Scope files. On the other hand, it makes available options for importing different other file formats and go through the data. Limited functionalityĪs the name suggests, LabChart Reader is a viewing utility, so it does not integrate the functionality available in the LabChart application it is not equipped with the possibility to record new data or save it.

The tool is not complicated and the installation process is a simple one, all the user has to do is follow the instructions on the screen and a few clicks later the software is available on the system.

It makes working with this sort of files easier by providing access to this sort of files in order to analyze it. LabChart Reader is a utility that can help users view LabChart data files without the need of the full-blown application.
