An amplifier has an input resistance of 1 k Ω, an output resistance of 200Ω, and a short-circuit trans-conductance gain of 0.5 S. Determine the open-circuit voltage gain, the short-circuit current gain, and the open-circuit trans-resistance gain.
The graph below shows a RHEED pattern during MBE for a structure that consists of the deposition of a layer of GaAs, followed by AlxGa1-xAs, followed by AlAs. What is the thickness of the AlAs and the GaAs layers ( in "monolayers")? What is the al..
Show that the time displacement in a periodic function has no effect on the magnitude spectrum, but changes the phase spectrum by an amount of -nω0τ radians for the component of the frequency nω0 if the time displacement is τ.
A, B,C and D are members of the board of trustees of an investment company. Decisions are made by the following criterions. A BUY order is placed if: · A, B and D vote no and C votes yes, · Or A and C vote no and rest vote yes,
1- Find F(s) for = A[ a cos(ßt) + b sin(ßt)] u(t) and plot and the poles and zeros in the S- plane. 2- find f(s) for = 2d(t) +4e^-2t cos(2t) u(t) and plot and the poles and zeros in the S- plane. 3- find f(s) for = 10[3-6t-4e^-2t] u(t) and plot and t..
How much resistance is required to limit the current to 1.5 mA, if a 6v battery is connected across the resistance
Explain the properties and the application of high resistivity materials related with tunsten and carbon?
F(a,b,c,d) = Σ m(7, 11, 12, 14) + Σ d(0, 10) (a) Find all of the prime implicants of F'. (b) Find a minimum product-of-sums for F. Note: F' is specified in (a) and F in (b).
b unit vector a θ dotted with unit vector a y (dotted means dot product) θ is from spherecial coordinates and starts from the postive z direction c unit vector a r crossed with unit vector a x (crossed means cross product).
Design a sequencer with an enabler with 3 outputs that when enabled follows a successive clock sequence of 000,000,011,011,110,110,010,011 when the last step is reached the sequence returns to the beginning.
Design a metering circuit to measure the line-to-neutral voltage and line currents on a three-phase four-wire, 4.16-kVswitchgear main circuit breaker rated at 2000 amperes.
A sinusoidal voltage source is zero at t = 0.2 microseconds and is "going positive" at that point, meaning that v(t') > 0 for t' = 0.21 microseconds. Furthermore, the voltage at t = 0 is -28 milliVolts and its next zero is at t = 8.2 microseconds
