Consider a uniform ring of charge, radius 'a' surrounded by n air gap a < r < b. the air gap is enclosed within a halo like disk b < r < c. The uniform surface charge densities on the center disk and the surrounding halo are the same.
The z direction is out of the plane of the paper.
Part a. Calculate the electric field intensity at a distance 'd' along the z-axis in terms of a,b,c, and d. Explain your reasoning. This result should be analytic.
Part b. Calculate the electric field intensity at a point off the z-axis at some z distance 'd' from the co¬ordinate origin.
Part c. Using MATLAB plot the electric field intensity for all points in the region around the disk.
Make a user interface (using matlab) for amplitude modulation and demodulation without using the ammod and demmod function. The program should ask the user the 3 types of message signal (Square ,sinc,sinusoidal, triangle, sawtooth)
Calculate the spectral efficiency. i.e.. the number of transmitted bits per unit bandwidth (or binary PAM, 4-PAM, and I28-PAM
assume filter is connected to a pure resistive load. The cutoff frequency is not to drop below 25krad/s. What is the smallest load resistor that can be connected across the output terminals of the filter.
A small house has three windows and two doors. Each window and door has a switch attached such that the contacts close when a door or window opens. Draw a ladder logic diagram that will turn on a light if one or more windows are open or if both do..
Provide an output V to indicate that at least one of the input ispresent. The input with the highest subscript number has thehighest priority. What will be the value of the four outputs if inputs D5 and D3 are 1 at the same time
Are these signals periodic, find their fundamental period T and their fundamental frequency, otherwise prove that they are non-periodic x(t)= 4 cos(12 t+400) + sin(16 t) x(t)=cos4t +3e-j12t x(t)= ej(10t+p/3) x(t)= ejt +ej3t +sin(6t)
A coaxial line is filled with a very slightly lossy material with a relative dielectric constant of 5 The line would have a characteristic impedance of 100 ohm if it was air-filled. (a) What is the characteristic impedance of the dielectric-filled li..
Given a char variable called gender, write C++ statements to output "Male" if gender contains upper or lower case M, "Female" if it contains upper or lower case F, or "Invalid Gender" if it contains anything else. Use if / else if statements.
A half-wave plate has a phase retardation of π. Assume that the plane is oriented so that the azimuth angle (i.e., the angle between the x-axis and the slow axis of the plate) Ψ=0. a. Find the polarization state of the transmitted beam, assuming t..
The 24-bit data field of a packet is given by 0xBC603F. The packet contains a CRC with the generator polynomial given by X 3+X+1 a) Find the CRC checksum. Provide the complete code-word including the checksum in hex.
A1. An amplifier has cutoff frequencies of 120.0 Hz and 1.200 kHz. Calculate the bandwidth and center frequency of the amplifier. A2. The upper cutoff frequency of an amplifier is 8.000 MHz and its center frequency is 1 MHz.
