A vibration trandsucer measures a sinusoidal signal with up to a 100-hz frequency and an amplitude of + and - 5 v. Superimposed on this signal is an additional signal with a freq of 1000 hz. and amplitude of .2 v. I want to attenuate the 1000 hz signal to 1% of its value using a butterworth filter. Using a corner freq of 100 hz select a filter order to preform this task.
A 190-F capacitance is initially charged to 1190V . At t = 0, it is connected to a 1-k resistance. a) At what time t2 has 50 percent of the initial energy stored in the capacitance been dissipated in the resistance
Describe the features of your organization that indicate which kind of organization it is. Describe five steps your organization could take to become better and move up in the scale. Do you think it is likely that this kind of change could happen ..
Description of Transformer, An 11 kV to 415 V transformer has a rating of 100 kVA. The winding resistance and leakage reactance when referred to the secondary are 0.0142 Ohm and 0.0569 Ohm respectively
Calculate the following. a) What is the magnitude of the voltage in a wall socket if the effective voltage is 240 Vrms b) What is the magnitude of the current if the effective current is 360 mArms
An inventor claims to have perfected an engine that wil produce power from energy transferred as heat from a 1000K flame. Energy wil be rejected as heat to the ground at 290 K. A 75 percent energy conversion efficiency is claimed.
resistor: a volt-ohmmeter with an internal impedance of 1000 Ω/V and an EVM with an impedance of 11 MΩ. Calculate the voltage indicated by each of these devices.
Use MATLAB to compute the inverse Laplace transform of X(s)=(s^2+2s+1)/(s(s+1)(s^2+10s+50)) and determine the value of x(t) in the steady state. How would you be able to obtain this value without computing the inverse? Explain.
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
A silicon semiconductor resistor is in the shape of a rectangular bar with a cross sectional area of 1x10^-6 cm^2 a length of 0.1 cm and is doped with a donor concentration of 5x10^16 cm^-3.
I)Design a circuit that gives you the following relation between input and output Vout = 2.17Vin + 5 Here are the constraints you need to work with: 1) Only one power supply that gives ±12V is available 2) Available op-amps run on ±12V
A 150 MVA, 24 kV, 123% three-phase synchronous generator operates with an induced voltage that is twice the rated line-to-neutral voltage. Calculate the three-phase steady-state short-circuit current at the generator terminals.
Racecar A is traveling on a straight portion of the track while racecar B is traveling on a circular portion of the track. At the instant shown, the speed of A is increasing at the rate of 10 m/s2, and the speed of B is decreasing at the rate of 6..
