1. This very-low-frequency sine- and square-wave generator requires few components, but provides low-distortion outputs (derived from LTspice simulator). The output of op amp U1 is applied to the ...

In this minimalistic square wave generator circuit, the RC network is composed of a 4.7KΩ resistor and a 100nF capacitor. So, we obtain a frequency of approximately 1.5kHz. Since the output square ...

Wave kinetic equation for fibre lasers Kinetic theory describes an average (macroscopic) probabilistic evolution of complex system. Starting from basic microscopic dynamic equations governing the ...
