Calculate the maximum power that can be sent through an a=2cm , b=1cm air-filled waveguide at 12GHz such that dielectric breakdown does not occur. Assume that the dielectric strength of air at atmospheric pressure is 3x10^6 [V/m]
Suppose that we define the value of the complex constant A as A = -2 + 2j. Write the constant A in magnitude-angle form, that is, find |A| and A such that A = |A|ej A Sketch the real part of the function z(t), where z(t) = Aej(500pit+pi/2).
A particle travels along the x-axis with postion ( measured in meters ) as a function of time ( measured in seconds ): x(t) = 5t^2-7t+2. (a) At what time or times is the particle at rest
Write a C-program to generate K-map row and column headings for an arbitrary number of row or column input variables, i.e. 4x4 k-map for 2 row and 2 column variables, 16x16 k-map for 4 row and 4 column variables, etc.
Let the random variable X denote the annual snow fall amount at a well known Utah ski resort. X has a normal distribution with mean 500 inches and standard deviation 50 inches. (a) What is the probability that in a given year the snow fall will be ..
A dc series motor of 230 V, 12 hp, 1200 rpm is connected to a 230 V supply. It draws a current of 40 A, and rotates at 1200 rpm. Ra = 0.25 ohms and Rs = 0.1 ohms. Assume magnetic linearity.
Design a combinational logic circuit which has one output Z and a 4-bit input ABCD representing a binary number. Z should be 1 iff the input is at least 5, but is no greater than 11. Use one OR gate (three inputs) and three AND gates
A digital oscillator delivers two sinusoidal signals at 10 kHz and 12 kHz, sampled at 60 kSa/s. What is the minimum FFT length N that will result in a leakage-free FFT if both tones are present?
For a 12-bit linear PCM code with a resolution of 0.02 V, determine the voltage range that would be converted to the following PCM codes. (a) 1 0 0 0 0 0 0 0 0 0 0 1 (b) 0 0 0 0 0 0 0 0 0 0 0 0
Teh energy stored in a 2H inductor os 130 J and is increasing at 200 J/s at t=4s. A) Determine the current magnitude at t=4s. B) Determine the voltage magnitude at t=4s.
Suppose users share a 1Mbps link. Also suppose that the traffic generation process of each user alternates (independently of the other users) between periods of activity (active modes), when the user generates data at a constant rate of 100 Kbps
What connectivity is required for both parties? Use your textbook and the Interne to research your answer. Which option would you suggest and why?
define a one-dimensional potential well having energies U as a function of position x as follows: U=infinity for x= -1nm to x=0; U=0 eV for x=0 to x=5nm; U=10 eV for x=5nm to x=7nm; U=0 for x>7nm and x
