The switch in Figure has been in position B for a long time and is moved to position A at t = 0. The circuit parameters are R1 =1kΩ, R2 = 100 Ω, L = 250 mH, C = 3.3 μF, and VA = 24 V.
(a) Find vC(t) and iL(t) for t ≥ 0.
(b) Is the circuit overdamped, critically damped, or underdamped?
(c) Use Multisim to validate your results.
Consider a (Nt,Nr) =(4,4) MIMO channel. For the input of the channel x = [x1,x2,x3,x4] assume that each xi is drawn from a BPSK constellation with energy P. Also assume that the channel noise variance is σ2 =1
The average intensity of sunlight reaching the earth is 1390W/m2. A charge of 2.38 x 10-8 C is placed in the path of this electromagnetic wave. What is the magnitude of the maximum electric force that the charge experiences
The average number of vacation days per year offered by different US companies is skewed to the right. A random sample of 60 companies showed the mean number of vacation days was 22, and the standard deviation was 9 days.
