The curved surface of a hemisphere of radius a centered at the origin carries a total charge of Q uniformly distributed over its curved surface. Find the electric field at a height h above the origin.
Suppose the above device is to be used as an 8-way power splitter (let's say only the top-most input is used). Let the input power be P. Assuming a cross-coupling coefficient of f and ignoring excess losses, what are the possible power levels Pi a..
Sketch a block diagram of the arrangement and calculate suitable values of pad resistance if both the amplifier and the line have a characteristic impedance of 600 Ohm.
Bipolar Junction Transistor, A silicon n-p-n bipolar junction transistor is designed with emitter, base and collector doping levels of 10^19cm, 10^15cm and 5*10^17cm, respectively.
The electron beam in a certain cathode ray tube possesses cylindrical symmetry, and the charge density is represented by:ρv= -0.1 / (ρ2 + 10-8) pC/m3 for 0
A Y-connected three phase supply has a balanced voltages of 110e^j0, 110e^(j2/3) and , 110e^(j4/3). The corresponding impedances on the Y-connected load are 30, 30+j40 and 40+j30 ohm.
From a high-level perspective, what is the major difference between the LM324 and the LF347. Which of the performance characteristics are significantly different because of this.
Consider a 4 channel CDM system with the following CHIPS: A: -1 -1 -1 1 B: -1 -1 1 -1 C: -1 1 -1 -1 D: -1 1 1 1 a) Show that each one of those chips is orthogonal to all of the others. b) If the CDM signal 1 -1 -3 1 is received, by all receivers, ..
