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
The temperature is 25 °C, the pressure 1 bar, and the relative humidity 85%. Determine whether the formation of the decahydrate according to the reaction below, Na2 SO4 + 10H2 O = Na2 SO4 · 10H2O, can take place under these conditions. What is ..
Consider a superheterodyne FM receiver designed to receive the frequency band of 1 to 20 MHz with an IF frequency 8 MHz. what is the range of frequencies generated by the local oscillator for this receiver
The venturi has a throat-to-inlet area ratio of 0.85. Calculate the maximum vacuum obtainable in the reservoir when the venturi is placed in an airstream of 90 m/s at standard sea level conditions.
an 8kg block is released from the rest on a frictionless incline of angle 60.if the speed of the box is 10m/s when it reaches to the ground what was the height of the initial point it was released
At 1 kHz, the skin depth in copper is 2 mm. Determine the a.c. resistance at 500 kHz and at 10 MHz of 20 cm lengths of copper conductors having the following cross sections:
What are the most common insulators used for extremely high voltages. Explain your answer with, at least, two points foreach insulator. Hint. they can withstand much highertemperatures than rubber insulation.
Design and Analysis: The simple high-pass and low-pass filters shown to the right have been analyzed in class. The transfer functions are H-HP(f) = j fRC / ( 1 + j fRC ) and H-LP(f) = 1 / ( 1 + j fRC ). In either case the -3dB frequencies are F-3D..
If an electric field in free space of 57.1 V/m makes an angle of 41 degrees to the surface normal of a dielectric slab with relative permittivity 4.01, what is the value of the electric field perpendicular to the surface just inside the slab
A voltage divider can provide a voltage at its output, but it cannot provide current. If a device is connected to the output of a voltage divider, what value of resistance should it have
Let the probability of a bit error be p, and the length of a data frame be N. Find the probability of 1, 2, 3, and 4 bit errors occurring in the frame. a) Tabulate the results for N = 1000, 10000, and 100000 bits, for p = 10-6, 10-8, and 10-14
Design and draw a ladder diagram circuit suitable for a PLC which will fulfil the control requirement - Explain briefly the technique of multiplexed switching of analogue signals.
