(a) h11 and h21 (b) h12 and h11 (c) h21 and h11 (d) None of these

2. A Signal x(t) has the Fourier transform
X(?) = { 1 for | ? | < }W . Its first zero-crossing in time domain occurs at:
O otherwise
(a) 1/pW (b) W ( c) p/ W (d) None of these

3. In a thyrister full converter feeding a continuous load current, what is the duration each thyrister conducts in a cycle?
(a) 60 0 (b) 90 0 (c) 120 0 (d) 180 0

4. In a three-phase induction motor, the rotor field runs at the following speed with Respect to the stator structure:
(a) At synchronous speed in the direction of stator field
(b) At a slip speed in the direction of stator speed
(c) At synchronous speed in a direction opposite to that of stator field
(d) At zero speed

Rest of the Questions are attached in below a word file which is free of cost for you
