Calculation
where
fu=1, 5MHz – the unity gain bandwidth taken from Multisim op amp model.
Conclusion
Calculated and experimental results are very
similar while the output is less than the op amp voltage swing. To
obtain the higher output voltage, the op amp voltage swing must be
increased.

Ticket No1 1)The characteristic is called output characteristic or volt-ampere charateristic of a Rectifier Diode. 2)Rectifier Diode. 3) A is called Anode and C is called Cathode. An Anode has positive potential and therefore collects electrons in the device. Cathode has negative potential and therefore emits electrons to anode. The symbol looks like an arrow that ponts from the anode to the cathode, and reminds that conventional current flows easily from the p side(anode) to the n side(cathode). BIASING. Forward biasing. If the current in a diode is too large, excessive heat will destroy the device. Even approaching the burnout current value without reaching it can shorten its life. Therefore manufacturer's data sheet specifies the maximum forward current, that diode can withstand. This average current IF is the rate a diode can handle up to the forward direction when used as a rectifier. Another entry of interest in the da

Thesis Kivimaa August 2022

Thesis “How is it possible to calculate IT security effectiveness?” Kristjan Kivimaa August 2022 1 Abstract In IT Security world, there is lack of available, reliable systems for measuring security levels/posture. They lack the range of quantitative measurements and easy and fast deployment, and potentially affects companies of all sizes. Readily available security standards provide qualitative security levels, but not quantitative results – that would be easily comparable. This deficiency makes it hard for companies to evaluate their security posture accurately. Absence of security metrics makes it complicated for customers to select the appropriate measures for particular security level needed. The research question for this research project is – “How is it possible to calculate IT security effectiveness?”. The aim of this research is to use this reference m

2-stroke tuners handbook tuners

Two-Stroke TUNER’S HANDBOOK By Gordon Jennings Illustrations by the author Copyright © 1973 by Gordon Jennings Compiled for reprint © 2007 by Ken i PREFACE Many years have passed since Gordon Jennings first published this manual. Its 2007 and although there have been huge technological changes the basics are still the basics. There is a huge interest in vintage snowmobiles and their “simple” two stroke power plants of yesteryear. There is a wealth of knowledge contained in this manual. Let’s journey back to 1973 and read the book that was the two stroke bible of that era. Decades have passed since I hung around with John and Jim. John and I worked for the same corporation and I found a 500 triple Kawasaki for him at a reasonable price. He converted it into a drag bike, modified the engine completely and added mikuni carbs and tuned pipes. John borrowed Jim’s cop
