| description | The article considers an effective algorithm for group delay
correction in the channels of multichannel information and
measurement systems. The description of the method is carried
out for the case of harmonics measuring for current and voltage
in electrical networks. The algorithm is based on the linear interpolation method using a non-recursive digital filter. The filter
coefficients are a discretized windowed sinc. After the description
of the method, the results of effective band modeling of the
interpolating filter are presented. In conclusion, recommendations
are given to reduce the amount of processor memory in the
implementation of the algorithm. |
