Show transcribed image text Q4. Suppose the circuit of Example 10.9 (page – 875) is modified as shown in the following figure. (a) Find the loop transmission L(s) and the characteristic equation. (b) Draw the root locus diagram for varying value of K. (c) Find the value of K for maximally flat response. (d) The value of K that makes the circuit – oscillate.
