Parameters:CorTec BIC Implant

Parameter Configuration

Source Parameters


The total number of channels: EEG.


Samples per channel per digitized block. Together with the sampling rate, this parameter determines how often per second data are collected, processed, and feedback is updated. For example, at 500 Hz sampling and a SampleBlockSize of 20, the system (e.g., source signal display, signal processing, and stimulus presentation) will be updated 25 times per second. For OpenBCI Cyton the sampling rate is 250Hz and it sends data to buffer every half second. So the suggested value for sample block size is 125. Note that more frequent updating than two times per second is not possible without altering the OpenBCI firmware.


The sample rate of the system. All data is either acquired at 250Hz In case you are experiencing problems by higher sampling rates (e.g., data loss, jerky display, etc.), increase the SampleBlockSize so that you are updating the system less frequently (usually, updating the system 20-30 times per second is sufficient for most applications), and increase Visualize->VisualizeSourceDecimation. This parameter will decrease the number of samples per second that are actually drawn in the Source display.


Offset for each channel.


Gain for each channel.
