An unpolarized beam of light is sent into a stack of four polarizing sheets, oriented so that the angle between the polarizing directions of adjacent sheets is 50 degrees. What fraction of the incident intensity is transmitted by the system?
Evaluate the following convolutions using the graphical approach: h1[n]=2u[n+1]-2u[n] h2(t)=2u(t+1)-2u(n) y1[n]={2u[n+1]-4u[n]}*h1[n] y2(t)={r(t-2)-2r(t-4)+r(t-6)}*h2(t) Evaluate the step response of h1[n] and h2(t)
If the output of the function generator for a sinusoidal waveform is 6 voltage divisions peak to peak and the voltmeter reads 2.12V, find the volts/div scale that is being used. If the frequency is 1 KHz and the peaks are 5 horizontal divisions ap..
Implement the truth table shown below using the minimum number of NAND gates. Use 2-, 3- , and/or 4-input NAND gates as required to minimize gates. Develop a logic circuit, using only NAND gates, to implement a circuit.
An electric field in free space is given as E=(x,4z,4). Given VA=10v, calculate the electric potential difference VAB & VB, where A is (1,1,1) and B is (3,3,3), assuming V=9 at (2,4,6).
Using Multisim, design a mod-100 BCD counter that drives a 2-digit, 7-segment display. The count sequence will be 0 through 99. Blank leading zeros in the tens digit of the display.
our senior design team is designing a force sensor to measure a force signal and analyze the signal with a microcomputer (binary system). The analog force signal is between 10 N and 70 N and has the frequency bandwidth of DC - 1000 Hz.
(a) The ideal delay system. y[n] = x[n-nd] (b) The accumulator system. y[n] = sum (xk) , k from -inf to n (c) Forward difference system. y[n] = x[n + 1]- x[n] (d) Backward difference system. y[n] = x[n]- x[n - 1]
Now assume that the doctor knows that 1 in 100 individuals with symptom G will have the rare disease, and he only orders the test when individuals have symptom G. Given that one of the doctor's patients tests positive.
A 2722-kg weight is being pushed up an inclined surface at constant speed by a cylinder. The coefficient of friction between the weight and inclined surface equals 0.15. for a pressure of 6.9 MPa, determine the required cylinder diameter.
Assume the motor is connected in wyne and that each branch can be represented by a resistance R in series with an inductive reactance X. (a) Calculate the value of R and X. (b) What is the phase angle between the line current
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
If the average heat content of the coal is 8,600 Btu/lb, and a typical coal-fired power plant operates at 40% efficiency, how many kW-hr of electricity was produced in 2010 using this coal
