For random ergodic voltage signal, I make a histogram of sample voltages and note that they form a Gaussian distribution. estimate the following moments over a number of samples taken at diffrent time points alont the voltage signal:
Mean Value: mv=0.5VStandard Deviation: ov=0.2V
Determine these signal parameters: DC voltage, AC power, and Total power.
Assume a 1 ohm load for the purposes of computing power in watts.
a. The mass of an electric car is 900 kg including the passengers. A single motor mounted on the front wheels drives the car, and the radius of the wheel is 0.3 m. The car is going downhill at a speed of 50 km/hr, and the slope of the hill is 30 d..
A baseband sine wave signal with frequency 4.0 kHz is modulated onto a carrier at 1.050 MHz using DSB-LC AM. What are the frequencies of the sidebands of the RF signal?
A volume is divided into two equal parts by a partition. The left volume has N atoms. The atoms have a mass m. A hole of area A is made in the partition at time t=0 A)Develop an expression for the number of white atoms on each side of the partition..
Bit 4 of Port B is connected to a switch that normally outputs a zero. Monitor this switch to detect a change from zero to one. Immediately when it becomes one, call a function to toggle Bit 5 of Port B, which is connected to an LED
A time varying capacitor is characterized by the charge- voltage equation q(t) = C(t)v(t)
determine that the total field B within the sample is one tesla. Calculate M and determine what percentage of the volume now consists of domains with magnetization parallel to the field.
1) Find the transient and steady-state responses of the system using frequency domain methods. 2) Find the forced and natural responses of the system using frequency domain methods. 3)Find the 0+ conditions for the system's step response and impulse ..
A Si bar is 0.25 cm long and 500 ?m2 in cross-sectional area. It is grounded at x=0 and biased at +20V at x=0.25 cm. Find the resistance and the current at 300K (a) when the Si bar is doped with 2×1017 cm-3 arsenic
If we want to correct the power factor to 0.9 lagging, what is the value of Q we need to inject.
Calculate the probability that the system will fail in 3,000 hours. Supposing no failure of any component occurs in 5,000 hours of operation. What would be your revised estimate of failure rates of the components in your system?
Solve the equation z^2+z+1=0 using z=(x,y) and the basic definitions. (Hint: Note that y does not equal 0 because the equation X^2+X+1 does not equal 0 for any real number x.)
Efficiency in a power transformer is 98.6% when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
