A system with transfer function G(s) = [(s2 + 9)(s + 2)]/[(s + 1)(s + 3)(s + 4)]is excited by sin(w t) . The steady-state output of the system is zero at
- The output Y of a 2-bit comparator is logic 1 whenever the 2-bit input A is greater than the 2-bit input B. The number of combinations for which the output is logic 1, is
- In the sum of products function f (X, Y, Z) = Σ(2, 3, 4, 5) , the prime implicants are

Consider the given circuit.In this circuit, the race around
- If x[n] = (1/3)|n| - (1/2)nu[n], then the region of convergence (ROC) of its Z-transform in the Z-plane will be
-
A capacitive motion transducer circuit is shown. The gap d between the parallel plates of the capacitor is varied as d(t) = 10-3[1 + 0.1 sin(1000 πt)]. If the value of the capacitance is 2pF at t = 0 ms, the output voltage VO at t = 2 ms is
- A psychrometric chart is used to determine
-
A strain gauge is attached on a cantilever beam as shown. If the base of the cantilever vibrates according to the equation x(t) = sin w1t + sin w2t, where 2 rad/s < w1, w2 < 3 rad/s, then the output of the strain gauge is proportional to
- The transfer function of a Zero-Order-Hold system with sampling interval T is
- An LED emitting at 1 ïm with a spectral width of 50 nm is used in a Michelson interferometer. To obtain a sustained interference, the maximum optical path difference between the two arms of the interferometer is
