Divide the wavelength into the velocity to calculate the frequency, expressed as described above as the number of cycles per second, or Hertz – written "Hz." For example, a water wave with a wavelength of 1 foot traveling at a speed of 4 inches per second has a frequency of 1/3 feet...
The fundamental frequency is the lowest frequency in a resonating system. It is a vital concept in musical instruments and many aspects of engineering. The harmonics of a given wave, for example, are all based on the fundamental frequency. In order to calculate a fundamental frequency, you need...
Waves can describe sound, light or even the wavefunction of particles, but every wave has a wavenumber. This describes how it varies through space, and this depends crucially on the wavelength of the wave or its speed and frequency. For physics or chemistry students, learning to calculate a w...
To figure these, you brain assessor? Calculate, student, calculate now! As the figuring gets longer, My friend, hope you get stronger And no figures incorrect allow! — Aaron L. Buchman,School Science and Mathematics, (c) 1953. You I sing, O ratio undefined By strict assay and lined, S...
The harmonic mean is more difficult to visualize, but is still useful. (By the way, “harmonics” refer to numbers like 1/2, 1/3 — 1 over anything, really.) The harmonic mean helps us calculateaverage rateswhen several items are working together. Let’s take a look. ...
From a thermal design perspective, put a thermal ground pad under the PLL chip to ensure that heat flows through the pad to the PCB and heat sink. Designers should calculate all thermal parameters of the PLL chip and PCB when used in extreme environments. ...
Let’s explore which parameters are most important when designing a buck (step-down) converter, and how to pair it with the best inductor available. We will also learn how to calculate basic parameters and explain some of the requirements for both switch-mode power ICs and inductors, includi...
Figure 4depicts the resulting control scheme. After using Equation 2 to calculate dFF, it is then added to the traditional average current-mode control output (dI). You could then use the final duty ratio (d) to generate a PWM waveform to control PFC. ...
