[Analytical estimation of the period of reverberator in an arbitrary model of an active medium]
Abstract:
Reverberators in an active medium with reduction were studied. Analytical estimations were obtained for reverberator period for arbitrary right parts of equations describing non-auto-oscillation active medium satisfying 2 natural conditions (existence of solutions as periodic flat waves, small dependence of the rate of such solutions on the wavelength). It was shown that the reverberator period under such conditions is given only by two parameters of the model: the minimal period of periodic flat waves and the rate of solitary impulse independent of the model of active medium. A comparison with numerical calculation of dimetric model of Fitz Hue Type was carried out.

RLC Circuit as a Damped Oscillator
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...

Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...

The effective value of a periodic current represents the direct current (DC) that conveys the same average power to a resistor as the periodic current itself. This concept is crucial when assessing AC circuits. To determine the...
