Oscillator

In technical analysis, a model for finding prices at which a security is overbought and oversold. An oscillator finds two extreme prices using various methods and finds buy signals and sell signals when the price of the security approaches each. One of the most common oscillators is the Stochastic oscillator. See also: Price ceiling, Price floor.

** Using an oscillator with fast startup allows shorter wake-up cycles and longer battery life compared to MEMS devices.
In general, there are various methods available to reduce the output noise of a ring oscillator. Some of these methods are intended to lower the effect of a specific noise source while others improve the overall noise characteristics of the circuits.
Kyocera developed the Z-Series clock oscillators to meet these demands while providing unprecedented flexibility in a standardized, quick-fulfillment solution.
Among the oscillators presented in Table I [3], the Microcomputer Compensated Crystal Oscillator (MCXO) seems to be the one that best fits with the frequency stability requirements, and also with the very low consumption demand.
where a is the periodic unit size, qaj is the j periodic phase factor, and [A.sub.1.sup.(0)][A.sub.2.sup.(0)] are the steady-state amplitude of shell and oscillator, respectively.
The authors are also grateful to Professor Michael Rosenblum for drawing their attention to the fact that, in paper [47], along with the suppression of synchrony in an ensemble of interacting units, stabilization of an active oscillator by means of a passive oscillator, included in the feedback loop, is also described.
For an ideal oscillator, [G.sub.T] ([G.sub.R]) boils down to the identity matrix [I.sub.N].
The frequency of the noise spur induced by the EMI occurs at offset frequencies that are aliases of the oscillator frequency.
These correspond to the period bifurcation cascades observed at the mentioned angles and, making a parallel with a common oscillator, it results evident that the extremes of the amplitude oscillations are far from being symmetrical at both sides of the equilibrium position of the chaotic oscillator.
From these system of equations, one can obtain approximate frequency-amplitude relationship of a nonlinear oscillator up to higher order.
In order to verify the theoretical analysis, the proposed oscillator has been simulated using HSPICE program by using TSMC 0.18 [micro]m CMOS process technology process parameters.
where [[psi].sub.j] is the phase of the oscillator number j; [[OMEGA].sub.1] and [[OMEGA].sub.2] are characteristic frequencies of excitatory and inhibitory neural oscillators population, respectively; [S.sub.1] ([[psi].sub.j]) and S2([[psi].sub.j]) are the external stimulations on excitatory and inhibitory neural oscillators, respectively; [M.sub.11]([[psi].sub.j] - [[psi].sub.k]) is the mutual coupling interactions between excitatory coupling oscillators; and inhibitory coupling oscillators [M.sub.12]([[psi].sub.j] - [[psi].sub.k]), [M.sub.22]([[psi].sub.j] [[psi].sub.k]), [M.sub.21] ([[psi].sub.j] - [[psi].sub.k]) [F.sub.j](t) are Gaussian white noise, able to meet the following second-order condition:
