parameters

  • <trc> parameter type: trace
    Trace to compute rms.
  • <lo-bound>, <hi-bound> parameter type: real
    Time window used for RMS calculation, if not defined all trace will be used.
  • <symbol> parameters type: output symbol
    Variable to take the resulting rms value.

example

rms 1 ;;; &g1
computed RMS value of whole trace 1 and puts result into variable G1
