The zero at - 1 gives the term (s + 1) in the numerator.
The poles at (- 2 + j1) and (- 2 - j1) give (s2 + 4s + 5) term is the denominator. Gain is 2.
3. A single phase half wave converter is feeding-a resistor load. The input voltage is v = Vm sin ?t. If firing angle is zero, the output dc voltage Vdc and output rms voltage Vrms respectively
4. In FM signal with a modulation index mf is passed through a frequency tripler. The wave in the output of the tripler will have a modulation index of
9. An amplifier without feedback has a voltage gain of 50, input resistance of 1 k? and output resistance of 2.5 k?. The input resistance of the current shunt -ve feedback amplifier using the above amplifier with a feedback factor of 0.2 is
