Hi,
We found that most of the activation signals turn out to be a “sinc-shaped” function. However, some strange activation signals show up in the data set as well, for example, the activation signal for T5-56000. Our question is, are these strange patterns correctly representing the real activation signal in corresponding scenario, or are they just caused by some mistakes made by the measurement?
Thank you,
Team Blue
Dear TeamBlue,
You might be referring to a truncated waveform. If so, then this is due to the limit setting on the data collection instrument. This happens because the gain for actuation signal was adjusted in order to get the best waveform for the received signal (ch2) because that carries the information along the wave propagation path. For each specimen, the gain was kept constant through the whole testing process.
