Draw Bode Plots By Hand

What is Bode Plot?

Bode plot is a graphical representation of a system to evaluate its stability and performance. It is a combination of two graphs on a log (logarithmic) paper and consists of a bode phase plot and a bode magnitude plot. They are both drawn as functions of frequency.
