The third angular frequency (2ωi, ω1+ω2) is equal to the sum of the first (ω1) and the second angular frequency (ω2).
The selected axis is orthogonal to the angular frequency axis.
The multiplier (21) corrects the offset angular frequency so as to cancel the angular frequency offset by multiplying the samples by the offset correcting signal.
The angular frequency ω0 of the drive voltage Vd is the series resonance angular frequency provided by an equivalent circuit on the output side of the driver (10).
The present invention relates to a flywheel having mass that is a function of its angular frequency.
The cylinder signal (ZS1, ZS2, ZS3, ZS4) is transformed into a cylinder frequency signal (FS 1, FS2, FS3, FS4) in an angle frequency range.
Signal information indicating the beginning of combustion in the associated cylinder (2, 3, 4, 5) is extracted from the cylinder frequency signal (FS 1, FS2, FS3, FS4) at at least one predefined angle frequency.
The transconductance of each transconductor pair is set as the product of a desired radian center frequency and the capacitance of the corresponding matched capacitors.
