The micro Doppler component is hard to be recognized near the first

harmonic frequency.

Where 'Zn' is the impedance of the filter network at the nth

harmonic frequency.

To improve the conversion gain of the single-ended circuit, a second

harmonic frequency reflector was added in the input matching side.

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.

Contract Awarded for Tissue harmonic imaging function, Or tissue harmonic imaging, 3 different ways of pure harmonic, Wideband harmonic, High precision and strengthen dynamic tissue harmonic, Convenient switching with clear

harmonic frequency, Visual display, Adjustable (please attached proof);

The relationship of unwanted

harmonic frequency and [[omega].

By analyzing wind farm harmonic model, the harmonica contents can be calculated by the software and differing means of reducing the harmonic contents can be found depending on the feature of the harmonic source; moreover, the origin could be traced by

harmonic frequency spectrum when problems occurring in the system.

Power systems designed to function at 60 Hz in the United States and 50 Hz in many other countries may experience unsatisfactory operation and, in some instances, failure when subjected to voltages and currents that contain substantial

harmonic frequency elements.

Interestingly, the mosquitoes adjust the harmonic resonance of their thoracic box to produce a

harmonic frequency that converges at a frequency that is the female's third harmonic (three times her fundamental frequency) and the male's second harmonic (two times his fundamental frequency).

In general, however, frequency multipliers include some unwanted fundamental and

harmonic frequency components.

3])

harmonic frequency is suppressed by the transmission zero frequency ([f.

such as in power amplifiers stimulated with a narrowband input signal, there is only one dominant large-signal input component present, whereas all other input components (the

harmonic frequency components) are relatively small.
