Various feature extraction methods are implemented within MultiSens Analyzer. The available feature extraction methods also depend on the version of MultiSens Analyzer that you have licensed.
| Feature | Description | Version |
| Area | Calculates the area of the response curve above the baseline (= value of first measurement point). | Base |
| AreaAt | Calculates the area of the response curve above a baseline. Allows to set start point, end point, and base line determination for the calculation. | Base |
| AreaMax | Calculates the area of the response curve above the baseline (= value of first measurement point) from the first point to the point at which the maximum of the response is reached. | Base |
| Average | Calculates the aveage of the response curve. | Base |
| Base | Returns the baseline = value of the first measurement point. | Base |
| Base3 | Returns the baseline = average of the first 3 measurement points. | Base |
| EndDev3 | Returns the difference between the maximum of the response and the measurement point that occurred 3 points before the maximum. | Standard |
| EndDev5 | Returns the difference between the maximum of the response and the measurement point that occurred 5 points before the maximum. | Standard |
| FindSig | Returns the maximum deviation to the baseline that is found between the start point and the end point. Start point, end point and the point where to determine the baseline can be set. Additionally averaging can be set, which will average for the selected number of measurement points to calculate baseline and signal. |
Base |
| Max | Returns the maximum of the response curve. | Base |
| Max-Min | Returns the span of the response curve. | Base |
| MaxDev | Returns the maximum derivative found in the response curve. The derivative is calculated by subtracting the predecessor point for each measurement point. | Base |
| Min | Returns the minimum of the response curve. | Base |
| PascalScript | Allows to write feature extraction algorithms in Pascal. | Professional |
| Sig/Base | Returns the Signal divided by the baseline. Signal is determined as the maximum deviation to the baseline in the response curve. Baseline is determined as the value of the first measurement point. |
Base |
| Sig/Base3 | Same as Sig/Base, but averages over 3 measurement points to determine signal and baseline. | Base |
| SigAt | Returns the signal at a measurement point. The signal is calculated by subtracting the baseline (= first measurement point) from the selected measurement point. Additionally averaging can be set, which will average for the selected number of measurement points to calculate baseline and signal. |
Base |
| SigAt-BaseAt | Returns the difference of two measurement points in the response curve. Typically this is used to calculate a signal at a certain point by subtracting the baseline that is determined at another point. Additionally averaging can be set, which will average for the selected number of measurement points to calculate baseline and signal. |
Base |
| Sig-Base | Sig-Base is determined as the maximum deviation to the baseline in the response curve. Baseline is determined as the value of the first measurement point. |
Base |
| Sig-Base3 | Same as Sig-Base, but averages over 3 measurement points to determine signal and baseline. | Base |
| T3dB | Returns the number of the measurement point, at which the signal has returned to 3dB (= 70%) of the maximum in the response curve after the maximum had been reached. The signal is calculated by subtracting the baseline (= value of the first measurement point) from the value of each measurement point. |
Standard |
| T50 | Returns the number of the measurement point, at which the signal has returned to 50% of the maximum in the response curve after the maximum had been reached. The signal is calculated by subtracting the baseline (= value of the first measurement point) from the value of each measurement point. |
Standard |
| T90 | Returns the number of the measurement point, at which the signal has returned to 90% of the maximum in the response curve after the maximum had been reached. The signal is calculated by subtracting the baseline (= value of the first measurement point) from the value of each measurement point. |
Standard |
| TMax | Returns the number of the measurement point, at which the maximum of the response is reached. | Base |
| W3dB | Returns the number of measurement points from the T3dB point to the point after the maximum when the response curve has again fallen below 3dB (=70%) of the maximum. | Standard |
