DC Motor Calculations, part 1 Now that we have a good understanding of dc generators, we can begin our study of dc motors. Direct-current motors transform electrical energy into mechanical energy. They drive de......
Laser Interferometer Overview In a laser interferometer the laser beam is split into two beams by a beam splitter. One of the beams is directed to a mirror located at a certain distance to provide a re......
Linear and Rotary Encoders Linear and Rotary Encoders An encoder is an electrical mechanical device that can monitor motion or position. A typical encoder uses optical sensors to provide a series of pulses t......
AC and DC Coupling Overview Each input can be selectively AC or DC coupled. DC coupling allows both DC and AC signals through, while AC coupling accepts only AC signals. Figure 4-15a shows a waveform......
Pulse Shaping to Improve Spectral Efficiency This tutorial is part of the National Instruments Signal Generator Tutorial series. Each tutorial in this series, will teach you a specific topic of common measurement applications......
Decibels Logarithmic representation of signal levels: decibel notation The subject of decibels frequently confuses the newcomer to electronics, and even many an old-timer seems to have occa......

DC Shunt Motors Electrical Diagram of a Shunt Motor The shunt motor is different from the series motor in that the field winding is connected in parallel with the armature instead of in series. Yo......
Fiber Gratings Overview Normal optical fibers are uniform along their lengths. A slice taken from any one point on the fiber would look very much like a slice taken from any other part of the fib......
