Assume a line voltage of 2,400 volts is connected to the primary of the three-phase transformer and the line voltage of the secondary is 240 volts. What is the turns-ratio of the transformer?
Suppose that after 24 h the voltage across a 100-F super capacitor is 4:75 V. What is the equivalent leakage resistance in parallel with the capacitor?
Assuming the feedback transfer function is not a function of frequency, determine the frequency at which the phase of the loop gain is 180 degrees.
In a DSB-SC amplitude modulation system, the message signal is m(t)=e^-3t*u(t-2) and the carrier signal is cos(2000pi*t). Find and sketch the Fourier transform of the modulated signal.
Write the assembly code to specify an array named src that holds values: 01, 23, 45, 67, 89, and an array of five variables named dst, then write the code to copy the values in array src to array dst.
The time has come for XelPharm to expand. The board of directors has purchased another warehouse for a second distribution facility. It's located in an industrial area, about eight miles from the company's headquarters.
Define customer relationship management and explain why customer relationships are so important today.
The diagram of FIGURE 2 shows a bi-directional opto coupler input interface circuit. When a supply voltage of 20 V is applied the LED carries a current and 2 V is dropped across it. Calculate the value of the LED current and the value of current t..
Consider a diode biased at 1 mA. Find the change in current as a result of a changing the voltage by (a) -10 mV, (b) -5 mV, (c) +5mV, (d), +10mV. In each case, do the calculations (i) using the small-signal model and (ii) exponential model.
1) What is the dynamic range for an 8-bit ADC 2) A device that responds to a small current or voltage change by activating a mechanical switch allowing a larger amount of current flow is a: a) transistor. b) transducer. c) solenoid. d) relay.
It is used in a quarter Wheatstone bridge with three other fixed 100 W resistors. If the strain gauge constant is 2.0, find the output voltage when the input voltage to the bridge is 10 Volts and the strain is 500 m strain.
Discuss how improvements in electrical conduction and/or advancements in magnets might affect the device you identified
Find the transfer function and the difference equation for a 2nd -order FIR filter that has unity d.c. gain, but for which the given input x(k) produces zero forced response. (Your filter will have a "notch" at the given frequency, and H(1) =1.)
