A certain nonmagnetic material has the material constantsεr = 2 andε′′/e′=4 × 10^-4 at ω =1.5Grad/s. Find the distance auniform plane wave can propagate through the material beforea. it is attenuated by 1 Np;b. the power level is reduced byone-half;c. the phase shifts 3600.
Compute the basic checksum, the 1's complement checksum, and the 2's complement checksum for each of the following groups of 8-bit data elements using both the basic calculation of the datasum and the one's complement datasum.
Find the equivalent impedance for Z1 = 60 L+60 and Z2 = 80 L-45 when these are connected in parallel What are the branch currents and the total circuit current if the supply voltage to the circuit is VS = 240V L0
The charge leaving the positive reference terminal of a voltage source is q(t)= [6sin120pi*t - 8cos120pi*t]mC the voltage source value is v(t)= 160cos120pi*t V. A) Determine the power supplied by the voltage source at t=0
Combine the following expressions into a single sinusoid and plot both the combined and original expressions in Matlab across 2 periods. a) 2cos(3t)-cos(3t-pi/4) b) sin(2t- pi/4) + 2cos(2t-pi/3) c) cos(t) - sin(t) d) 10cos((pi*t) + pi/3) + 8cos((p..
A school has 100 lockers and 100 students. All lockers are closed on the first day of school. As the students enter, the first student, denoted by S1, opens every locker. Then the second student, S2, begins, with the second locker denoted L2, and ..
An amplifier has a gain Ad,dB = 40 dB. Its common-mode rejection ratio is CMRRdB= 120 dB. It is used to amplify an input which has a 200mV desired signal along with an undesired common-mode signal ("noise").
A 415V 50 Hz three phase supply has been divided into three balanced loads, as follows: LOAD 1 (STAR): 15 kVA at a power factor of 0.60 lagging; LOAD 2 (DELTA): 24 kW at a power factor of 0.55 lagging;
Starting from the expression for the MOSFET unity-gain frequency, fT=gm/2*pi*(Cgs+Cgd) and making the approximation that Cgs>>Cgd and that the overlap component of Cgs is negligibly small, show that for an n-channel device fT=3*un*Vov/4*pi*L^2
A 2400-115V transformer has a sinusodial flux expressed by φ=0.113 sin 188.5t. determine the primary and secondary turns.
What is the advantage of using a double-break contact instead of a single-break contact?
A system has a characteristic equation: q(s) = s3 + 20s2 + 5s + 100 = 0 Determine whether the system is stable using the Routh-Hurwitz criterion. Determine the roots of the characteristic equation.
