Write a computer program to find the time duration of a low pass energy signal that contains a certain specified percentage of its total energy, for example, 95%. In other words, write a program to find T in the equation
with ET set equal to a specified value, where it is assumed that the signal is zero for t
Simulating shadow fading. Simulate a sample path of a shadow fading process for equispaced samples on a straight line. Assume a correlation distance Dc = 500 m and a standard deviation of σz = 7.5 dB (these values are from Gudmundson's paper).
The base class must also have a virtual print() function that displays the class name. Randomly assign print functions in three other classes that display the class name. Create 7 pointers of the base class and have them point to all the classes.
A series combination of two capacitances, valued 0.2 μF and 0.6 μF initially discharged, is charged to 10V. find the charge and energy stored in each capacitance.
A computer has a 32-bit instruction word broken into fields as follows: opcode, six bits; two register fields, five bits each; and one immediate operand/register field, 16 bits (a) What is the maximum number of operations that can be specified
Show how to build each of the following single- or multiple-output logic functions using one or more 74X138 or 74X139 binary decoders and NAND gates. (hint: Each realization should be equivalent to a sum of minterms)
a DC series machine ( 9.25 kW, 185 V, 1500 RPM) has Ra+Rsr = .3 ohms. The data for the magnetization curve are: Ia 0 10 20 30 40 50 60 Ea 10 50 106 156 184 200 208 Determine the terminal voltage at Ia = 20 amps, 40 amps and 60 amps.
Assume that an additional inductance can be inserted in series with the load. also assume that the converter has no freewheeling diodes. Calculate the added inductance that leads to a conduction period of 180 degrees when alpha = 30 degrees.
A 117 V(rms), 60Hz household circuit has two 75 Watt lights,PF=1, and a fan using 500VA at 0.78 PF (lagging). A) Draw the circuit, representing each load by its impedance. Include the switches for each load. B) Determine the total current required fo..
Interfacing a Transducer to an Analog-to-Digital converter
A torque of 10 N.m is applied to a uniform disk shaped flywheel. The flywheel has a mass of 20kg and a radius of 0.5m. At t=0, the flywheel is at rest. How much energy is stored in the flywheel at the end of 20 sec
1. use microsoft excel to compare costs from at least three different vendors and reasons to accept specific bids.
A phasor current of (1 phase angle 0 degrees)A is flowing through the series combination of 1 ohm, 1H, and 1F. At what frequency is the amplitude of the voltage across the network twice the amplitude of the voltage across the resistor
