Computes an estimation of the AC and DC levels of the input signal. Details
![]() |
initialize, when TRUE, initializes the internal state of the VI. |
![]() |
signal is the input time-domain signal usually in volts. |
![]() |
sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than zero. |
![]() |
AC estimate is the estimate of the input signal AC level, usually in volts rms when the input signal is in volts. |
![]() |
DC estimate is the estimate of the input signal DC level, usually in volts if the input signal is in volts. |
![]() |
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions. |
The AC & DC Estimator PtByPt VI routine performs spectral analysis to the extent that it separates DC, bin 0, from AC, the rms sum of the rest of the bins.
