Unformatted text preview: 0.5 on a single graph of the complex splane). b) Determine the value of the gain K for which the system is stable. (Note: You should determine the critical value of K to at least two significant digits.) c) Select the value K=2 and separate the transfer function into two terms by an expansion in partial fractions. Then, determine the analytic form for the inverse transform ( 29 { } 1 ( ) t T s= T L valid for K = 2 . Hint: You should seek to express T(s) in the partial fraction form 2 2 ( ) ( ) A Ms N T s s a s σ ϖ + = + + + + ....
