In comparing the operation of the half-controlled 2-pulse circuit with that of the fully-controlled circuit, which of the following statements are evident? 1. Since half the thyristors are replaced by diodes, a half-controlled converter costs less than a fully-controlled converter. 2. Due to the freewheeling action with a half-controlled bridge-circuit power factor is improved in half-controlled converters. 3. The AC supply current is more distorted due to its zero periods with the half-controlled circuit, compared to a fully-controlled bridge circuit. Select the correct answer using the code given below :
S1 and S2 are two DT systems which are connected together to form a new system. Consider the following statements: i) If S1 and S2 are non-causal, then S is non-causal ii) If S1 and/or S2 are unstable, then S is unstable The correct statement from the above is ____________
Assertion (A): An LTI discrete system represented by the difference equation. y (n+2)-5y(n+1)+6y(n) =x(n) is unstable. Reason (R): A system is unstable if the roots of the characteristic equation lie outside the unit circle.
