Finding the variance of the real part and imaginary part of the DFT series: Z(wk) = n^(-1/2) * Summation from 1 to (n-1) of (Yt*e^(-itwk) where Yt are iid having variance p and mean zero
Find the Laplace transform of a rectangular voltage pulse that is 0 V until time 0 s, then jumps to 5 V and stays there until time 2 ms, then returns to 0 V and stays there after time 2 ms. Hint: express the pulse in terms of unit step functions.
Provide a simple class definition and then provide the syntax and the rationale for declaring an array of objects of the class. Also explain the dimension of the array and why you chose that number of elements for the object array.
Design a continuous time system to generate output y(t)=sin(wt)u(t) when the input is a unit step function. Specify the system using a differential equation.
a voltage v(t) = 24cos(2000t-45degrees) is applied across a parallel connection of a 5kΩ resistor and 100nF capacitor. find the steady state current ic(t) through the capacitor and ir(t) through the resistor.
1. Find the Fourier transform of the signal by hand, using either the de nition of the Fourier transform or properties of the Fourier transform. 2. Use the Symbolic Math Toolbox to nd the Fourier transform and show that the same result is obtained.
In a right triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sides. Stephanie has the integer lengths of three sides of a triangle and needs to know if it is a right triangle.
RC ciruit= Current course (3u(-t) A) in parrallel to 6k ohm resistor and 5uF cap. Determine the instantaneous power absorbed by the resistor at t=(0); 30ms; and 90ms.
The charge carried by an electron is ?1.60×10?19 C. Suppose that an electron moves through a voltage of 120V from the negative polarity to the positive polarity. How much energy is transferred Does the electron gain or lose energy
In the plane z=5 there is a ring with a 3cm radius with its center on the z axis. The ring has a uniformly distributed charge Q. The origin 0,0,0 is at a small sphere with a mass of 0.5kg and a charge of -Q.
A part hollow non conducting sphere has a uniform volume charge density of 200 nC/m2. Find the potential difference between the inner surface at r=2cm and outer surface at r=5cm
A proportional controller for a rotating antenna has a gain Kp of 5 in-oz/deg. The antenna was initially pointing due south, but was then commanded to point southeast. What is the torque when the antenna gets to within 5o
