WebJun 1, 2024 · A one-cycle sine wave has been widely used as a substitute for a fling-step earthquake ground motion [[23], [24], [25], [26]].Although the one-cycle sine wave effectively expresses the main characteristic of the fling-step motion, the iteration of the time-history response analysis is required to obtain the critical resonant maximum responses of … WebThe base acceleration for the 50-g, 11-ms half sine shock. The computed response spectra for 5% damping (Q = 10) is shown below. The absolute acceleration response spectrum …

WebMay 6, 2024 · So, I was trying to mess with noise cancellation on my arduino (I think I did it wrong now that I remember) but at the time I was wondering if it was feasible to generate a pseudo-sine (or triangle) wave (but mostly sine :D) by rapidly switching PWM duty cycle. I know a 16mhz AVR can do PWM at 8mhz(fixed), which is plenty fast enough for these … WebMar 21, 2014 · A triangle is easy to generate simply by charging and discharging a capacitor with a constant current. It also isn’t too far from a sine wave with only 12% distortion. Rather than simply filtering the triangle, it can be “shaped”. This is something illustrated by the late Hans Camenzind in his “Designing Analog Chips” book. google spell check dictionary

WebOct 2, 2005 · #1 The simplest way to get this pair of devices working in a non-400hz 3-phase environment seems to be to program a pic to generate three-phase and amplify the output. If I have three pins per phase and run each through a resistor of some calculated value I can make a psuedo-sinewave.
