FTU's hardware of key part is 80C196KC20 and the hardware extends 8kROM, 32kROM, 2kE2PROM24LC16B, two pieces of MAX125, real time clock DS12887, read and write control logic equipment EPM7128SQC100Q, LCD controller 6963c.
A high speed data acquisition in a design of portable memory- oscillorgaph with 100M analogue frequence range was fulfilled, in which ARM was used for data processing and sys- tem control with high speed, FPGA for carrier of digit circuit, MC12429 for programmable frequence clocks, ADC9288 for ADC chip , the prototype of machine developed showed the design was feasible.
According to the measure results, the ADPLL can operate from 108MHz to 304MHz, and the peak-to-peak jitter is 220ps when the DCO output is 188MHz, and can supply clocks for 32 bits RISC microprocessors.
Further, we formally introduce the notion of a logical time system (a logical clock) and proceed to discuss the properties of the scalar, vector, and matrix clocks.
High accuracy of local clocks is also necessary for operation of network protocols (for energy-saving purposes, the nodes spend most of the time in the sleeping mode and communicate only occasionally).
Possibility of precision experimental verification of time retardation in moving clocks by using coherent excitation of relativi
We also present the results of the first experiments in which Larmor clocks were used to measure the neutron tunneling time in the resonance of a quasi-bound state and the Bragg diffraction time.
The effects of elastic collisions in optical-lattice atomic clocks are analyzed.
One-hour shifts of the acrophase of this rhythm towards earlier hours in the spring and in the opposite direction in the autumn could be related to the practice of changing the clock to winter and summer time.
It is shown that the correct adjustment of the phase shifts of the clock signals of the lock-in amplifiers can considerably reduce the effect of the instability of the photon-coupled pair signal on the result of measurements.
For the dissipated energy W and the clock rate f, it is found that W ～ fαC1 + αΣ as f tends to infinity, where α is essentially less than unity.
The clock frequency of the generator of topologically modulated pulses developed is chosen such that the ratio of the wavelength at the clock frequency to the dimensions of the standard switch card is equal to 104.
For loading and unloading of boats or ships round the clock, the access channel and its expanded part - a port are excavated on the lagoon and ocean reef flats in the tropic Pacific oceanic islands.
