Let consider the wireless cellular systems with cluster size N=19.
1.Find the co-channel reuse ratio.
2.If the number of total duplex channels is 600, with the bandwidth of 60 kHz each (in duplex)
a)find the single cell capacity.
b)find the total bandwidth required for wireless system
3.Find the signal-interference ratio in dB when omnidirectional antenna is used and the propagation coefficient n =3.
4.Find the signal-interference ratio in dB when 120-sectoring antenna is used and the propagation coefficient n =3.
5.If a cluster is replicated 10 times within the system, find the total number of users that can be served with this wireless cellular system
design an arithmetic incrementer/decrementer circuit. Your circuit will recieve a 3-bit binary number (A) as input to produce an output which is either A+1 or A-1 depending upon the command input (ID).
One side of the transformer bank is connected to a 120-kV transmission line, and the other side is connected to a three-phase load of 10 MVA at 13.2kV and 0.8 lagging power factor. Using the base in the tranmission line of 120-kV and 20 MVA.
Consider the first-order linear differential equation y(t) + 5 (dy(t) / dt) = x(t) Compute the zero-input response (general solution of the homogeneous equation) to find the system-specific part of the response
Describe your understanding of the similarity and differences between MOSFET and BJT, in terms of 1) terminal behavior, 2) i-v characteristics, 3) amplifier configuration, 4) small-signal equivalent models and 5) biasing technique.
Noise is generally viewed as one of a number of general biological stressors. It is felt that excessive exposure to noise might be considered a health risk as noise may contribute to the development and aggravation of stress related conditions suc..
The magnitude of the current in a RL circuit decreases at a rate of 2000 A/s at t=0 and 100 A/s at t=.2s. At what time has the energy stored in the inductor decreased 1 percent of its intial value.
A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstable filter.
Identify the type of cable that is permitted in single- and multifamily dwelling units but that cannot be used underground, nor in buildings that are more than three stories above grade, nor in commercial garages, motion picture studios, theaters,..
A series type Ohmmeter uses a 50 ohm, 1mA PMMC the internal battery voltage is 3V the desired scale marking for half scale deflection is 2000 ohm. Calculate:- - Value of R1 & R2
Design a low pass active filter that passes frequencies at 900 Hz and below and at these values the magnitude (in dB) of the transfer function is 20+-3(between 23 dB and 17 dB). The circuit's magnitude (in dB) of the transfer function at a frequen..
An FM signal being transmitted is represented by eFM(t) = 50Sin((2)(95.1)(106)t+2Sin((2)(10)(103)t)). If the antenna impedance is 75 , determine: (a) total power in FM signal and (b) FM modulation index.
Build a series circuit consisting of a 130 V 60 Hz ac source, a 5 ohm resistor, a 53.05 mH inductor, and a 0.33156 mF capacitor. a) Draw the ac circuit diagram b) Sove for the phasor current and phasor voltages across each component.
