Perform a link budget for a 25-kilometer point-to-point microwave link in the 30 GHz band. Calculate the free space loss (dB), received power dBm), fade margin (dB), and Fresnel zone radius(m) given the following:
Tx Power = 70 dBm
Tx and Rx antennas diameter = 4 m
Antenna efficiency coefficient = 0.5
Antenna polarization = Vertical
Cable (feed line) loss coefficient = 0.8dB/m
Cable length from Tx to antenna (feedline) = 5m
Cable length from Rx to antenna (feedline) = 8m
Atmospheric losses = 0.5 dB
Receiver sensitivity = -100 dBm
Rain intensity for 0.01% outage = 30 mm/hr
The voltage drops across three resistors in series are measured to be 10.0V, 15.0V, and 25.0V. If the largest resistor is 47.0 ?, what is the value of the smallest resistor?
A transmission line is specified by the following, while operated at omega w=6*10^8 rad/s, L'= 0.4*10^-6 H/m, C'=40*10^-12 F/m, G'=80*10^-6 S/m, and R'=20 ohms/m. Find the attenuation rate after a wave propagates 10 meters on this line.
Performance Analysis of 16 Bit by16 Bit MAC design using 5:3 Compressors - 3:2 counters and 4:2 compressors have been widely used for multiplier implementations.
Locate and specify an appropriate sensor if it is to operate at 120 vac as an input to a PLC. Create the ladder diagram program to accomplish the specified control.
If L=0.0053nH, C=15µF find the operating frequency of series LC circuit. What factors decides capacitance? Explain using diagram.
Find the density for germanium (Ge) semiconductor atoms give that its lattice constant a-5.66Å (Angstrom) and atomic weight is 72.59 g/mole.
The signal transmitted by a Base Station has a power of 1 mW at a distance of 1 m from the transmitter. Measurements have shown that the propagation exponent for the path loss is n=3 up to a distance of 1 km and n=4 beyond that.
On any given day, the price of stock XX can do one of three things: jump very high, fall very low, or stay reasonably close to its opening value. You are trying to use Bayes' Law to determine if stock XX is being bought or sold by shareholders
calculate the average signal-to-noise (SNR) in decibels (dB) Assume equal numbers of binary 0s and 1s.
Suppose a 12-V battery bank rated at 200 Ah under standard conditions needs to deliver 600 Wh over a 12-h period each day. If they operate at -10 Celsius, how many days of use would they be able to supply
Now assume that the doctor knows that 1 in 100 individuals with symptom G will have the rare disease, and he only orders the test when individuals have symptom G. Given that one of the doctor's patients tests positive.
For a given lithium ion battery, it can supply 0.85 ampere-hours, or 850 (mAh) with a constant output voltage of 3.6 (V). How much energy is stored in this lithium ion battery. How much energy is imparted to an electron that flows
