... 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...

... switching at high frequency; if the ground point of the high energy side of the circuit is directly connected to the ground of the low energy side of the circuit, switching noise may propagate through ... from the positive terminal to the negative terminal. The supply is through the brushes, which make contact with the commutator segments. From Faraday’s laws of electrom...

... to hold constant the value of the signal being converted. At the instance the sample is to be taken, the T /H holds the sample value even if the signal is still changing. Once the conversion has ... of the transducer (the measurement) is not linear, it is linearized by the signal conditioner.] The element of the transducer which senses the controlled output is call...

... 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 ... types of basic devices that can be represented this way, based on the relationship between the power variables on the two ports. For either type, a relationship between two of the...

... 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...
