Description

Selects the method used by a SIRC filter to preserve noise. The selections are:

  • PRMS. Applies preserve RMS noise handling where the noise magnitude is kept the same as the channel.
  • SPECtrum. Applies process spectrum noise handling where the filter increases or decreases the noise based on whether SIRC is increasing or decreasing bandwidth. The noise power spectrum is assumed to match the channel response. This was the method used before revision A.06.60.

Requires FlexDCA revision A.06.60 and above.
