Abstract

The possibility of the compensation of amplitude and phase errors of data acquisition channels is investigated. The complex passband error can be significantly reduced by an appropriate digital filter, as it is illustrated on the example of a dynamic signal analyzer. The aspects of IIR and FIR equalizers are studied: it turns out that for the given antialiasing filter (Cauer filter, order 11) an FIR filter of length 60...100 can perform as well as a 26/26 IIR one. Because of the absence of stability problems and the ease of implementation, the use of FIR filters is suggested.
