The structuring of the twelve interlinked all-interval rows has as yet not been considered: By analogy to the overtone relationships to a fundamental tone, Stockhausen subsequently expressed the eleven intervals of the series as proportions.
(22.) Stockhausen relates the expressions "fundamental duration" and "fundamental pitch" to the traditional concepts of meter and rhythm in this way: "The difference between metre and rhythm is exactly that which we discern between the 'fundamental tone' and the 'tone-colour' of sound-spectra: the fundamental phase (metric fundamental) is defined by the periodic main intensity-maxima (the heaviest accents), and these result from the formant-structure.
Usually the determined frequency is DC +[f.sub.inst] or the fundamental tone
, -[f.sub.inst], and design knowledge of the circuit leads easily to the proper value.
While the levels are often set at 6 dB below the 1 dB compression point, the preferred in-house method is to reduce the level of the two fundamental tones by 10 dB to preclude any possibility of gain saturation during the brief periods when the tones are in phase and the peak envelope power (PEP) is 6 dB above the level of either tone.
In actual practice, to measure 31M, the two fundamental tones are set at a level of 10 dB below the 1 dB compression point of the amplifier.
The simulator allows designers to specify any number of fundamental tones
for analysis and to co-simulate EM, linear and non-linear circuits.

For example, there is no limit to the number of fundamental tones
used in the analysis.
The cancellation of the fundamental tones
and the distortion products as a function of the phase error is limited by the expression 
These distortion spectra are a result of the interaction of all three fundamental tones
, that is, [kf.sub.1] [+ or -] [mf.sub.2] [+ or -] [nf.sub.3].
