Stray Capacitance Effects: Stray Capacitance Effects (Cs) at the input terminals of an operational amplifier effectively introduces an additional phase-lag network in the feedback loop, (see Fig. 15-17), thus making the op-amp circuit unstable. Stray…
Strain Gauge Load Cell Working Principle: Strain Gauge Load Cell - The Load Cell is used to weigh extremely heavy loads. A length of bar, usually steel, is used as the active element. The weight…
Strain Gauge Factor Derivation: The Strain Gauge Factor Derivation is an example of a passive transducer that uses the variation in electrical resistance in wires to sense the strain produced by a force on the…
Storage Oscilloscope (For VLF Signal): Storage Oscilloscope - Storage targets can be distinguished from standard phosphor targets by their ability to retain a waveform pattern for a long time, independent of phosphor peristence. Two storage…
Stereo FM Multiplex Reception: Assuming there have been no losses or distortion in transmission, the demodulator output in a Stereo FM Multiplex Reception, tuned to a stereo transmission, will be exactly as shown in Figure…
Stepper Motor Interface: A stepper motor is a digital motor. It can be driven by digital signal. Fig. 15.18 shows the typical 2 phase Stepper Motor Interface using 8255. Motor shown in the circuit has…
Stepper Motor Classification: The Stepper Motor Classification based on the construction and principle of operation. These are Variable reluctance motors Permanent magnet motors Hybrid stepping motors Claw pole motors with permanent magnets The stepper motors…
Stepper Motor Applications: The microprocessors are employed for the control of stepper motors which are generally used as position actuators. Some other Stepper Motor Applications are to drive floppy discs, numerical control of machine tools,…
Step up Step down Chopper or Buck Boost Converter - Working Principle: A chopper can also be used for stepping up or down the supply voltage by varying its duty cycle. This is also known…
Step Up Converter or Boost Converter: A Step Up Converter, or boost converter, produces a dc output voltage higher than its supply voltage. In the circuit shown in Fig. 17Â-34(a), L1 is directly connected to…
