Suppose you go to a consultation meeting with a potential client.The client requires a single beam antenna with HPBW's of theta1 = 15 degrees in one plane and theta2 = 30 degrees in the other plane. During the meeting, the potential client mentioned that they are thinking toremove all amplifiers (about 40dB gain) in the system in order to save cost and improve systemefficiency. Your boss, who is not the antenna expert, replies, "That's ok! We can just compensatefor this by increasing the antenna gain. We can just increase the antenna gain to 50 dB." As theantenna expert, do you speak up? What do you say? Does a gain of 50 dB make sense with theclient's requirements? Note: Use the relationship between gain and HPBW.
As the ball rises, it gradually loses kinetic energy as its potential energy increases. At the top of its flight, when its vertical speed goes to zero, all of the kinetic energy has been converted into potential energy.
you borrowed $10000 from a local bank with the agreement that you will pay back the loan in five years the pay back plan includes two parts: a graduated payment plan with the first payment set at 1500 at year 1 and a gradient of $600 afterward
A dc shunt machine is connected to 220 volt supply and is running at speed of 1200 r.p.m . its armature current is 60 amp and the torque of its shaft is 95 Nm . show whether the machine in running as a motor or generator.
Use a 74LS283N Adder chip and a 74LS86N XOR chip. Simulate the circuit in Multisim and test enough input combinations that you are sure the circuit is working properly. Make sure you test in all theranges of numbers that are possible.
a) How long does it take for the soprano's voice to reach the listener b)In the same time interval, how far form the soprano has the sound wave in the auditorium traveled. Take the speed of sound to be 340 m/s.
20 pts using the symbol table on the right show the lc-3 assembly language generated by a non- optimizing c compiler
A. Determine the fundamental frequency w0, the period t0, and the coefficients in the representation X(t) = x0 + Re{(sigma)k=1N Xkejkwot} for the above input. C. Now consider a new signal y(t) = x(t) + 10 cos (50 pi t - pi/6). How is the spectrum ..
A wafer 100mm in diameter is mounted in an electron-beam evaporation system in which the spherical radius is 40cm. Use Eq. 6.7 to estimate the worst-case varation in film thickness between the center and edges
An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 10.5 m/s in 3.60 s. (a) What is the magnitude and direction of the bird's acceleration
Design a circuit with four single-bit inputs X, Y, T, and Z, but only one single-bit output E. A two bit control code word S0S1 selects which of the four inputs is propagated to the output (the selection code is not unique).
The conductance of a wire is 100 S. If the area of the wire is increased by 2/3 and the length is reduced by the same amount, find the new conductance of the wire if the temperature remain fixed.
