+#X text 21 131 Principle of operation: Well \, this is what is usually
+done to estimate SISO transfer functions using te FFT.;
+#X text 21 171 The avaraging mode used here deserves some explication:
+When you turn the estimation on (by checking the "run/stop" button)
+\, linear averaging will be performed until the chosen number of averages
+is reached. Once it is reached \, averaging continues in an exponential
+fashion \, by weighting;
+#X text 21 -4 pm_tfsiso.pd;
+#X text 21 363 When you press the "save" button \, the real and imaginary
+parts of the transfer function as well as the coherence will be saved
+to seperate files (the filename you give will be appended by _hre \,
+_him and _coh \, respectively).;
+#X text 21 273 Note that the displayed overlap percentage is truncated
+to an integer value. The actual values result from halving the offset
+between subsequent blocks (until te minimum value of 64 samples). For
+example \, with nfft=1024 \, possible overlap values are 0% \, 50%
+\, 75% \, 87.5% and 93.75% \, corresponding to offsets of 1024 \, 512
+\, 256 \, 128 and 64 samples \, respectively.;
