A unity feedback system has the loop transfer function

Sketch the Bode plot of the loop transfer function and indicate how the magnitude 20 log |L(jω)| plot varies as K varies. Develop a table for K = 0.75,2, and 10, and for each K determine the crossover frequency (ωc. for 201og|L(ω))| = 0 dB), the magnitude at low frequency (20 log|L(jω)| for ω « 1), and for the closed-loop system determine the bandwidth for each K.
