Disclosed is a pulse wave propagation speed measurement device (10) which detects, at a reference time detector (2), reference times (T1, T2) of the starting wave component (S1) and the reflected wave component (S2) of a pulse wave (S), and which detects, at a pulse wave amplitude ...
We analyze the control of the propagation speed of three wave packets interacting in a medium with quadratic nonlinearity and dispersion. We find analytical expressions for mutually trapped pulses with a common velocity in the form of a three-parameter family of solutions of the three-wave resonant...
In this article Tyto Robotics explains how to increase (or decrease) electric motor speed, motor speed in terms of Pulse-Width Modulation (PWM) duty cycle and Electronic Speed Controller (ESC) output voltage, and the motor KV to RPM calculation. Electric motors are used in many tools and veh...

This video discusses PWM—pulse-width modulation—and two different architectures to implement PWM control for controlling the speed of a BLDC motor. PWM is a square wave signal that repeats itself at a certain frequency. Each PWM cycle is called a period, and the percentage of time the ...
Answer to: The fundamental frequency of a standing wave on a 1.0 m long string is 440 Hz. What would be the wave speed of a pulse moving along the...

(delta primary, delta and wye secondary) and each secondary feeds one of two paralleled six-pulse converters, a 12-pulse front-end is created with all the benefits mentioned above. 18-pulse designs are also available. Because of the extra cost, this type of solution tends to only get us...
