Kyocera developed the Z-Series clock oscillators
to meet these demands while providing unprecedented flexibility in a standardized, quick-fulfillment solution.

From Figures 11 and 12, all the shells and oscillators
of this periodic structure have achieved steady-state vibration.
"Our goal is to reach a system with hundreds of oscillators
, which would put us in striking distance of developing a computing substrate that could solve graph coloring problems whose optimal solutions are not yet known to mankind," Datta said.
The waveforms of the mean variable (x)(t) (Figure 3(a)) and of the individual oscillators
, say [x.sub.1] (t) (Figure 3(b)), look nearly the same, since the array is synchronized.
To verify this, we run simulations of a hybrid beamforming system with independent oscillators
using the QuaDRiGa channel model .
In this section, we describe the experimental methods used to compare the resilience of the MEMS oscillator
to several commercially available quartz oscillators
IDT said that its MEMS oscillators
utilise its patented piezoelectric MEMS (pMEMS) resonator technology, which combines the strong electromechanical coupling of a piezoelectric material with the stability and low damping of single-crystal silicon to create a passive frequency source of unparalleled performance and reliability.
