This is done by showing that every sequential circuit operating in synchronous mode can be transformed into an equivalent sequential circuit operating in fundamental mode with the same number of internal states.The basic idea is to consider, for both the major types of sequential circuits, circuits...
The Ubitron is a traveling-wave amplifier based on the interaction between a 1arge-diameter magnetically undulated electron beam and the TE01 mode in circular waveguide. The interaction, is of the periodic beam type, which is sometimes r... RM Phillips - Macmillan Education UK 被引量: 0发表...
Based on a simple series expansion method involving the Chebyshev technique, we compute the fractional modal power guided inside the fibre core and also the excitation of the fundamental mode in the case of single-mode graded index fibres with examples of step and parabolic index cores. Relevant ...

pulse of laser beam instantaneous thermal expansion and contraction occur due to the particle’s optical absorption. The expansion and contraction generate an acoustic wave that can be received by the ultrasound transducers. As photoacoustic imaging (PAI) has become an emerging and fast-growing ...

the authors performed an experimental study with a flow phantom.While changing the mechanical index and the sound insonation mode (continuous and intermittent), images were obtained with three contrast-enhanced ultrasound techniques: fundamental, second-harmonic, and pulse-inversion harmonic imaging (PIHI...
When the load is large (current is used), the cycle-constant PWM control is employed, and when the load is light, the cycle-variable PFM control is used (current is not used). ■PWM (Pulse Width Modulation): The frequency is constant, and the output part's control mode is triggered ...
We have examined the effect of chirp and phase noise on the formation of solitons in optical fibres. The Zakharov-Shabat direct scattering problem is solve... KJ Blow,D Wood - 《Optics Communications》 被引量: 59发表: 1986年 Non-transform limited pulse locked radiation mode radiation generator...
If I have a pulsed laser with 10 μJ pulse energy and the beam is Gaussian, is that energy the average energy or the peak energy? Would the energy at tip of the distribution (the center of the beam) be equal to 10 μJ or less by a factor? The author's answer: Pulse energy is...
