1. We consider a Rayleigh fading signal. Suppose that a single branch receiver has a 10% chance of being 5 dB below a certain SNR threshold γo. a) Determine the mean of the Rayleigh fading signal as reference to the threshold mentioned in the above, i.e., γo. b) What is the probability that the receiver signal will be 8 dB below γo if b1) a single branch receiver b2) a two branch selection diversity receiver b3) a three branch selection diversity receiver, or b4) a four branch selection diversity receiver is used, respectively
If the surface heat flux varies linearly with x, such that q"s (W/m2) = 500x (m), what are the values of q, Tm,o, Ts,i, and Ts.o? Sketch the axial variation of T, and Tm. On the same figure, also sketch (qualitatively) the axial variation of Ts an..
If β=100, and Vin=0.2cos(2πf*t)+2 V where f=100 Hz, compute what you would expect for Vce. Assume Vcc=5V, Rb=20 kΩ, Rc=200 Ω from the given image.
You are asked by your supervisor to witness factory tests to be performed on 15 single-phase transformers that your company plans to purchase. The 15 single-phase transformers will be used to make five three-phase banks.
In an FM line of sight link , the frequency is 6 GHz and the beamwidth = 27 MHz the transmitting and receiving antennas have a gain of 33 dB , the receiving antenna is 40 Km apart from the transmitting station
A saw, fan, and lube pump all go on when a start button is pressed. Pressing a stop button immediately stops the saw but allows the fan to continue operating. The fan is to run for an additional 5 seconds after shutdown of the saw.
Find the max instantaneous power delivered by the source, dissipated by R, and absorbed by L. What are the smallest instants (t > 0) at which these maxima occur.
An object of mass m = 0:1 kg is dropped from a high tower. Suppose the magnitude of the force due to air resistance is 0:98v2. (The gravitational constant is g = 9:8 m s2 ). a) Write down the dierential equation satisfied by velocity.
the decimal digits 0 to 9 are represented by an 8421bcd code.derive a boolean expression for a logic circuit which
(a) Design a simple PNP current source to give an output current of IO = 0.5 mA (nominal value). The transistor parameters are f = 50, VEE = 10 V, VCC = 10V, |VBE| = 0.7 V, |VCEsat| = 0.3 V and VA = 50 V (for all transistors)
A parallel-plate capacitor has a plate sepration of 0.025mm and ceramic dielectric with \(\epsilon r= 250. \) Determine the plate surface area in square meters if C= 10 \(\mu F\) What are the basic physical configurations of a capacitor
An active-loaded NMOS differential amplifier operates with a bias current I of 100 microamperes. The NMOS transistors are operated at Vov=0.2 V and the PMOS devices at |Vov|=0.3V. The Early voltages are 20 V for the NMOS
Inverse Z-transform and poles and zeros. When finding the inverse Z-transform of functions with z-1 terms in the numerator, the fact that z-1 can be thought of as a delay operator can be used to simplify the computation.
