B) asymptotic frequency
C) gain cross over frequency
O D) gain frequency
O E) phase cross over frequency
Proposed an industrial application with a transfer function. Using the proposed transfer
function:
1. Sketch the corresponding magnitude and phase asymptotic Bode plot by hand (Using
semi log paper).
2. Plot the corresponding Bode plot in MATLAB and verify that the result corresponds to
you hand-sketched asymptotic plot.
