In simulating multipath fading channels it is important to calibrate the simulations. It is a common practice to normalize the power profile p(τ) and the doppler spectrum S(λ) in order to have unit areas.
(a) Find the value of a for normalizing an exponential power profile of the form
(b) Find the value of K needed for normalizing the Jakes doppler spectrum.
(c) Find the area under the Ricean doppler spectrum defined by (14.61).
Explain how the semiconductor behaves as n-type
A power amplifier can be represented by a current source in parallel with a 200ohm resistance. An 8-ohm loudspeaker is connected to the power amplifier via an audio transformer so that maximum power is transferred to the loudspeaker. What must be ..
To Design a Low Voltage Switchboard (with examples and diagrams expalantion )
Determine the value of Rw required to null the bridge when the applied weight on the scale is zero kg and Determine the bridge signal voltage ΔV when the applied weight onthe bridge is 999 kg
the rms voltage of a balanced 3 phase Y connected source is 110 volts at 60Hz. it is connected to a balanced Y Load by 3 distribution lines with an impedence on each line z=1+j2. the load impedence is z=19=j28 per phase.
Assume two cables have wire strands that are the same diameter and made of the same material. If one cable has 7 strands and another has 19 strands, which will have more resistance over a mile
The hydraulic grade line throughout the system.
A meter has a resistance of 100Ω and gives a full scale deflection when it carries a currentof 25 μA. (a) What resistor, Rx, would you connect in parallelwith this meter in order to construct an ammeter which gives afull-scale deflection for a cur..
The op-amp in the input stage of a certain isolation amplifier has a voltage gain of 30. The output stage is set for a gain of 10. What is the overall voltage gain of this device?
You have the questions and their solutions. You need to write different way of answers, now you have enough time, and time should not be an issue for you.
What is the velocity of the final body and what is its mass M?
Find VDSQ and IDQ for the FET shown in Figure, given Vto = 3 V and K = 0.5 mA/V2. Find the value of gm at the operating point. Draw the small-signal equivalent circuit, assuming that rd =∞. Derive an expression for the resistance Ro in terms of RD..
