If a lowpass filter with a DC gain of 1 and 3 poles, all at 3KHzis used as an antialiasing filter, at what frequency will the aliased signal ( 5KHz) appear abd wgat will be the amplitude of the aliased signal.
define a one-dimensional potential well having energies U as a function of position x as follows: U=infinity for x= -1nm to x=0; U=0 eV for x=0 to x=5nm; U=10 eV for x=5nm to x=7nm; U=0 for x>7nm and x
Consider LTI system described by input-out relationship below y(t)=u(t) times integral(from minus infinity to t) (x(tau)) d(tau) a) Determine impulse response ,h(t), of the system without using Fourier and Laplace transform tools.
What is the motor efficiency as operated?
For each one of the 3 frequency responses, H(f), in parts (a), (b), and (c) do the following: i. Obtain the system's impulse response, h(t). ii. Indicate if the system is BIBO stable or not, and state why. iii. Indicate if the system is causal or not..
1-phase 2-winding transformer is rated 30 kVA, 360/90 V, 60 Hz. A source connected to the 360-V winding supplies an impedance load connected to the 120-V winding. The load absorbs 15 kVA at 0.8 p.f. lagging
(a) GivenX=(00111)2 and Y=(00110)2 , compute the carrybits using the equations for a CLA. How many time units would youneed to compute all the carry bits and why (b). Compute all the sum bits usingthe aforementioned carry bits.
a bar of n-type germanium and we place an E field going to the right across it and create a pulse of excess minority carriers (holes) in the center of the bar at time t=0. In other words we are performing the Haynes Shockley Experiment on the bar
For a certain population of students taking the Miller Analogy test, it is found that the scores are normally distributed with a mean of 50 and a standard deviation of 5. What is the score on this test that is the cutoff value for the top 12 perce..
an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal = 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input (b) SNR at the output (c) Noise figure
Next find a 95% confidence interval for the proportion theta of defective chips and also find a one sided 95% confidence interval for the proportion of defective ones. Refering to this problem, how large a ssample should be taken
AC Analysis Gain at Midband (with bypass capacitor in circuit) Connect the bypass capacitor using the switch.
Why is pulse shaping filtering indispensable in wireless communications applications. Give three reasons why pulse shaping filters are used and in what points of the communications link they may be deployed.
