Assuming zero initial condition, the response y (t) of the system given below to a unit step input u (t) is
- The impulse response of a system is h(t) = t u(t) . For an input u(t -1) , the output is
- Which one of the following statements is NOT TRUE for a continuous time causal and stable LTI system?
- Two systems with impulse responses h1 (t) and h2 (t) are connected in cascade. Then the overall impulse response of the cascaded system is given by
- A source vs (t) = V cos 100 πt has an internal impedance of (4 + j3)Ω . If a purely resistive load connected to this source has to extract the maximum power out of the source, its value in Ω should be
- A single-phase load is supplied by a single-phase voltage source. If the current flowing from the load to the source is 10∠-150oA and if the voltage at the load terminals is 100∠60o V, then the
- A single-phase transformer has no-load loss of 64 W, as obtained from an open-circuit test. When a short-circuit test is performed on it with 90% of the rated currents flowing in its both LV and HV windings, the measured loss is 81 W. The transformer has maximum efficiency when operated at
- The flux density at a point in space is given by B = 4 xax + 2kyay + 8 az Wb/m2. The value of constant k must be equal to
