... inputs. On the other hand, sequential systems represent the class of circuits in which the outputs depend not only on the present value of the inputs, but also on the past behavior of the circuit. ... FFs and latches. Table 41.1 shows the behavior of each of these types. Flip-Flops and Latches The outputs of the FFs or latches, which are sequential devices, are determin...

... least ±60° phase margin. The above gain margins apply to simultaneous and independent gain perturbations when the loop is broken at the output. The same holds for the above phase margins. The above ... some time the fascination with artificial neural networks, and achievements in the mathematical foundation of the back- propagation algorithm by Werbos (1974) went unnoti...

... I wish to express my heartfelt thanks to all the contributing authors. Taking time in otherwise busy and hectic schedules to author the excellent articles appearing in the Mechatronics Handbook ... Mechatronics Handbook is much appre- ciated. I also wish to thank my Advisory Board for their help in the early stages of planning the topics in the handbook. This handb...

... with an electron is rather small. This, of course, has to do with the size of the unit we use to measure charge, the coulomb (C), named after Charles Coulomb. However, the definition of the ... of mass (I G ), then Steiner’s theorem (parallel axis theorem) relates this moment of inertia to that about another axis a distance d away by I = I G + md 2 , where m is the mass of...

... The number of equations one obtains by this technique is equal to the number of meshes in the circuit. All branch currents and voltages may subsequently be obtained from the mesh currents, ... sources, on the one hand, and parallel and series circuits, on the other. This duality appears again very clearly in the analysis of equivalent circuits: it will shortly be shown that equi...

... frequency. Most high stability units use either the third or fifth overtone to achieve a high Q. Overtones higher than fifth are rarely used because they make it harder to tune the device to the desired ... During this time, the performance of the oscillator continuously changes until it reaches its normal operating temperature. The temperature within the oven then remains constan...

The supply is through the brushes, which make contact with the commutator segments. From Faraday’s laws of electrom...
