  • Frequency Devices Glossary of Terms
    for BAND-PASS or BAND-REJECT filters. Group Delay: The instantaneous rate of change of phase with respect to frequency of a filter, usually shown in a phase versus frequency plot. Harmonic: A signal whose frequency of interest is an integer multiple of the fundamental frequency, i.e. F = fundamental, 2 x F
  • Frequency Range
    Network analyzers measure an application's fundamental frequencies, harmonics, or spurious signals on the high end, and baseband or intermediate frequency (IF) signals on the low end. Applications such as wireless communications require higher frequency capabilities. Some cellular standards require
  • Waterfall Analysis: Frequency Spectrum or Order Spectrum?
    samples/second which was swept in 10 seconds from 10 Hz to 100 Hz (corresponding to the fundamental rotation frequency of 600 to 6000 rpm).  This simulated a signal that has frequency components of 1X, 3X, 5X, 7X, and so on… times the fundamental frequency.  A second signal was also created to serve
  • Optimized Lightning Protection for Higher Frequencies (.pdf)
    . more expensive than lower performance. alternative protectors. Figure 5 il us-. trates how the lightning let-through of. a quarter wave protector for 5 to 6 GHz. has a low peak voltage and resulting low. energy. Also, the fundamental harmonic. content associated with the output has. a frequency
  • A Simple Frequency Response Function
    blog. This conversion is one of the fundamental laws of Newton’s physics. It is possible to convert from Acceleration to Velocity to Displacement using calculus, specifically integration. Our Prosig software performs this conversion in an advanced fashion to take account of the constant and remove

  • How High in Frequency Are Accelerometer Measurements Meaningful
    . conceptualized. In 1976, at Sandia National Laboratories, the request. have a fundamental sensor resonance below 100 KHz. In 1983. for an extremely high frequency acceleration measurement was again. Endevco Corporation designed a series of MEMS (Micro Electro-. presented to the author. The goal
  • Ultrasonic Cleaning: Fundamental Theory and Application
    ), variable duty cycle, and amplitude control at a single frequency. All of these variables allow control of gross, or macroscopic, variables, such as raw power, into the fluid. The latest class of aqueous cleaning technology allows all of the aforementioned parameters, but at multiple center frequencies
