Accordingly, pulses with very short durations (i.e., very small fractions of the modulation period [T.sub.p]) could arise from the necessity to shift the pattern to a harmonic frequency
of high order (e.g., [??] > 3) and could be hard to realize in practice.
For frequency part, there are narrow band signals which are clock harmonic frequency
, amplitude modulation signal, and wide band time dependent signal.
A slight difference between the average values of the dominant harmonic frequency
of the distress calls was observed in the Bay 47, regarding the time of the day (nocturnal = 1 505.39Hz e diurnal = 1 251.18Hz, U = 46.5, p<0.01).
Where 'Zn' is the impedance of the filter network at the nth harmonic frequency
. The harmonic voltage 'Vf' across the series active filter.
To improve the conversion gain of the single-ended circuit, a second harmonic frequency
reflector was added in the input matching side.
In addition to standard products, PSPL also offers custom comb generators to meet specific input frequency range, output power, harmonic frequency
roll-off and form factor requirements.
The bats' ears have an exquisite sensitivity to their own harmonic frequency
. The researchers calculated that such differences in echolocation render prey of particular sizes or at certain distances invisible to one subspecies but not to another.
Application of current across a transducer in the handpiece causes the blade to vibrate at its harmonic frequency
of 55,000 Hz.
To initially determine how much vibration is required for a given part, a force inducer and sensing transducer are connected to it and the harmonic frequency
of the part measured.
The harmonic model of the DC wind turbine generator (WTG) under 20 Hz perturbation (harmonic frequency
) in MVDC network is identified by connecting to the MVDC network at t = [t.sub.1].
In the sound emitted from the mouth, the dB level of the second harmonic frequency
(2[f.sub.o]) is greater than the dB level of the fundamental (first harmonic) frequency [f.sub.o].
