Voltage and Harmonic Control of Inverters: Voltage and Harmonic Control of Inverters - In applying Inverters for motor control both V and f (keeping V/f constant) need to be varied. Further, the inverters apply essentially…
Voltage and Current in Series Resonant Circuit: The variation of impedance and current with frequency of Voltage and Current in Series Resonant Circuit is shown in Fig. 8.7. At resonant frequency, the capacitive reactance is…
Voltage and Current Divider Rule: Voltage and Current Divider Rule is explained by two conditions, namely Voltage Division in Series Circuit of Resistors Current Division in Parallel Circuit of Resistors Voltage Division in Series Circuit…
Voltage Amplifier - Definition and Equivalent Circuit: Voltage amplifiers are intended to amplify an input voltage signal and provide an output voltage signal. The voltage amplifiers is essentially a voltage-controlled voltage source. The input impedance…
Visual Display Units (VDUs): Large arrays of characters can be built up using alphanumeric devices, already discussed, but the number of connections and the complexity of the drive-logic circuitry increase significantly, although large-scale integrated (LSI)…
Viscosity Unit: Viscosity Unit is the property of a fluid which determines the amount of resistance to a shearing stress. A real fluid has no viscosity but it is nonÂexistent. Viscosity can also be defined…
Virtual 8086 Mode in Microprocessor: The virtual 8086 mode is a special operating mode of the Pentium processor and it is a subset of protected mode. In this mode, two 8086 application programs can be…
Video Test Pattern Generator: A pattern generator provides video signals directly, and with RF modulation, on standard TV channels for alignment, testing and servicing of TV receivers. The output signal is designed to produce simple…
Vestigial Sideband Modulation System (VSB): A Vestigial Sideband Modulation System (VSB) is actually a compromise between DSBSC and SSB modulation systems. In other words, it can be said that it is an optimum choice in…
Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning at 15,750 Hz. For either…
