We have an inductance L with an initial current of zero and the voltage across the inductance is given by v(t) = Vm cos( ωt). Suppose that ω is very large ideally, approaching infinity. For this voltage, does the inductance approximate either an open or a short circuit? Explain.
Discuss three classes of amplifier operation. Provide practical examples.
Choose the best answer for what a DC blocking or coupling capacitor does, assume the capacitor value is chosen to be too small. Blocks the DC and is relatively high impedance to the AC voltage. Blocks only the AC voltage going ..
Two components of linear distortion produced by transmitting asignal through an LTI (linear time invariant) system: Amplitude distortion - the frequency components of the input signalare transmitted through the system with different amounts of gain..
Explain with necessary derivation and EM details, why depletion layer charge appears when two dissimilar semiconductors(such as P and N materials) are combines to form a common junction.
construct a block diagram and an ASMD chart for a digital systemthat counts the number of people in a room. The one doorthrough which people enter the room has a photocell that changers asignal x from 1 to 0 when the light interrupted.
Determine the minimum oxide thickness in the field region (the field-oxide thickness) needed to prevent current leakage between neighboring MOSFETs. Neglect the oxide charge, and consider aluminum gate (the worst-case scenario).
by using the laplace transform compute the convolution xtvt of the two signals where xte-tut and vtsin
A 300-km bundled 500-kV, 60-Hz, three-phase completely transposed overhead line has three ACSR 1351-kcmil conductors per bundle, with the bundle spacing 0.5 m. The horizontal phase spacings between bundle centers are 10, 10, and 20 m.
what is the new resistance level of a copper conductor wire if the lenght is changed from 200 ft to 400 ft, the area is changed from 50,000 CM to 0.10 in ^2 and the original resistance was 7 ohms
A point charge of +Q is placed at the center of a square and asecond point charge of -Q is placed at the upper left corner. It isobserved that an electrostatic force of 2.0 N acts on the positivecharge at the center.
The output of the power supply should be a 5 Vdc with no more the 5 mV peak-peak ripple. 3) The output must be galvanically (transformer) isolated from the input, but NO 60 Hz transformers are to be used. 4) The load can be assumed purely resistiv..
A baseband sine wave signal with frequency 4.0 kHz is modulated onto a carrier at 1.050 MHz using DSB-LC AM. What are the frequencies of the sidebands of the RF signal?
