The second audio frequency range is narrower than the first audio frequency range, and the second frequency range contains the Helmholtz frequency of the transducer unit (20).
The invention also relates to a regeneration for reducing transient reactions in the frequency range, whereby the signal in the frequency range is impinged by an oversampling factor m.
The microprocessor (128) can determine if the driving frequency signal is within a desired frequency range and terminate startup if the driving frequency signal is not within the desired frequency range.
A scanning sequence is initiated in the first frequency range and a second frequency range to identify one or more access points in one or more channels to facilitate communication.
The frequency range has a width of several times the lower limit frequency of the frequency range, for example 800-2200 MHz.
A range of frequencies includes a central frequency selected to rapidly heat the composition.
Items having a specified frequency range of less than ± 0.05 % around their centre frequency are defined to be incapable of channel frequency switching.
The circuit (10) is sensitive to a preselected frequency range of the magnetic resonance field, such as a field having frequencies centered around the Lamor frequency.
The range of frequencies extends from a value below the nameplate frequency to a value above the nameplate frequency.
The ultrasound noise may be provided as an ultrasound frequency tone or as a range of frequencies that have been multiplied with an audio frequency.
This capacitor effectively improves low frequency response for a given length of transmission lines and decreases mismatch in an entire frequency range.
