By controlled tilting of immobilized ctenophores in either body plane with video recording of activated comb rows, I found that higher beat frequencies
occurred in the sagittal than in the tentacular plane at orthogonal orientations.
Should a master fail, ordinary LVDT signal conditioners in a master/slave hookup will revert back to their own oscillators, subjecting them to the beat frequencies
the master/slave hook up was supposed to prevent.
Split frequencies, beat frequencies
and other mixed frequencies are noise to our signal.
The power of the combined beam is measured by a fast photodetector, and the output of the detector then contains beat frequencies
Knowing that mackerel and eels swimming in water generate and thus experience different hydrodynamic environments, the duo simulated these different environments by varying tail beat frequencies
and fluid viscosity (syrupiness).
An array of ICs can be synchronized to a system clock to eliminate beat frequencies
Chair and scene motion frequencies and the resulting beat frequencies
are presented in Table 1.
These methods include mode locking of laser diodes; generating mm-wave beat frequencies
between two tunable lasers; using the laser diode's nonlinearity to upconvert data signals (laser diode mixing); using the photodiode's nonlinearity to up or downconvert data signals, also using the harmonic frequencies can produce substantial bandwidth improvement; high frequency narrowband electro-optic modulation; simultaneously using direct laser modulation and narrowband carrier modulation on EOMs for upconverting data signals; and utilization of laser diode harmonics by using large modulation indices.
The bidirectional synchronization input on the MAX5071A/MAX5071B allows multiple power supplies to operate at the same frequency, eliminating the undesirable beat frequencies
that result when power supplies are operated at varying frequencies.
