Given an analog signal x(t) 5cos(2pi*500t), for t>or equals 0. sampled at a rate of 8,000 Hz(a). sketch the spectrum of the original signal;(b). sketch the spectrum of the sampled signal from 0 kHz to 20 kHz.
A load consists of a resistance R in parallel with a capacitor of reactance X. The load is fed from a single phase supply through a line of impedance 8.4 + j11.2 ohms. The rms voltage at the load terminal is 1200 at 0 degress V rms,
Induction motor Y connection at 60Hz with the following: A.) 400 kVA induction motor running at 80% load with effeciency of 96% and p.f.=.88 b.) 40kW resistance heating source
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
Assume the widths of the two sides of the junction are much greater than the respective minority-carrier diffusion length. Calculate the applied voltage at a forward current of 1 mA at 300K.
A bowling ball is placed on a coil spring. The spring constant is 400N/m. When the bowling ball is placed on the spring, the spring compresses down 0.1m. If the spring is vertical how far will the bowling ball go
Suppose we have a causal LTI system with rational system function H(s). We don't know H(s), but we do have the following information: i. When the input to the system is x(t) = u(t), the output y(t) is absolutely integrable.
Write the full equations to light the bottom segment of a 7-segment display. INLCUDE the hexadecimal digits too ( b, c, d, and E ). Then simplify the equations using a k-map and draw the final circuit.
A complex electric field vector is given by E¯(¯r) =A/k * (ˆxk(z) - zˆk(x))e^-j(k(x)x+k(z)z) , where A is a complex number and k = µ is the real magnitude of the wave vector ¯k. a. What is the wave vector ¯k? b. What is the magnetic field
A knight is riding across a 12.0 m uniform drawbridge as shown in the figure. The right end of the bridge is held up by a cable and the left end is supported by a hinge. The mass of the rider and horse is 355 kg and the mass of the bridge is 493 k..
write a MATLAB program that will allow the user to type the power in watts, the mass of the object in kilograms, the height the object will be raised in meters, and the time it took to raise the object in seconds.
Write a short essay on your genre (ACTION) and its importance to the film canon. Use specific examples of films that illustrate its importance (you don't need to limit yourself to films you watched for this class).
The forces 20N,30N,40N,50N and 60N are acting on one of the angular points of a regular hexagon towards the other five angular points taken in order. Find the magnitude and direction of resultant force
