Negative feedback and Applications using Operational Amplifier
... One solution may consists of cascading many RC filters, using buffer amplifiers (as indicated in Fig. 12) to avoid loading effects. It turns out, such an approach produces indeed steeper rolloff, but the curved “f3dB knee” in the gain vs frequency response does not disappear. On the other hand, filt ...

Pulse Width Modulation
... Now, imagine you're able to flick the power switch ON/OFF fast enough. If you can time your ON/OFF flicking just right (of course it's difficult), the light bulb will actually dim instead of flicker. The ON/OFF cycle is known as the duty cycle. Below are the visual representation of 50%, 80% and 20% ...

Torque Improvement in Brushed DC Motors by using Four Pole
... Arrangement of winding pattern is important as number of poles is four. Traditionally for core DC motors coil is wound in two ways, one in lap pattern and other in wave pattern. In lap pattern, two ends of coil are terminated to adjacent segments. This pattern would require use of 4 numbers of brush ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
