An amplifier operating from +/- 12 V power supplies has alinear transfer characteristic except for output saturationat+/- 11.4 V.a) The peak-to-peak value of the largest sinusoidal wave thatcanbe applied at the amplifier input without output distortion is0.2V. Find the amplifier voltage gain in V/V and in dB.b) What is the corresponding output power for a 10 W load?c) What is the power gain, in W/W and in dB, if the inputpoweris 5 mW? What is the current gain of the amplifier, in A/A and in dB?d) What is the amplifier efficiency (in %) if the DCcurrentdrawn from each supply is 600 mA?
A silicon diode has a doping profile such that ND = ax3. What is the depth of the junction assuming the p side is uniformly doped with NA per cubic cm. Assume the x origin is at an ideal ohmic contact on the n side of the diode.(assume T=300K).
draw the sympol and truth table of the gate that corresponds to the action of the logic gate.
In a particular technology, a small BJT operating at vBE = 28VT conducts a collector current of 100 µA. What is the corresponding saturation current. For a transistor in the same technology but with an emitter junction that is 32 times larger.
If 50.0 cm of copper wire (diameter 1.00 mm) is formed into a single circular loop and placed perpendicular to the uniform magnetic field that is increasing at a constant rate of 10.0 mT/s, at what rate is thermal energy generated in that loop.
Assume a receiver is located 10 km from a 50 W transmitter. The carrier frequency is 6 GHz and free space propagation is assumed. Assume the unit gains for the system gains. Find: a) The power at the receiver
A natural gas power plant has a condenser that extracts 28,000 Btu/kg of natural gas. Compute the mechanical energy of the turbine and the overall system efficiency
1.How is crude oil formed ?How is it found/discovered ? 2.How is natural gas formed? (Start with plankton) and include crude oil formation.
Why do you think we need both rectangular and polar forms. There still seems to be some confusion about the relationship between R, Xc, OR XI and the phase angle. Take a value for R and a value for XC that is ten times smaller than R and find the..
a) The input of Hex- to - seven segment decoder is 1010. what will the display show. b) A priority encoder has all inputs activated. Which input will be encoded. Why.
