Here, we implemented the bode plot of a second-order network for the comprehensive understanding of the readers. Which means that phase plot would be a straight line with -90. $G\left( j\omega \right)H\left( j\omega \right)=K$ For gain factor K, the bode-plot is obtained as: We will discuss above elementary factors one by one: Gain factor KĪ constant K may be considered as complex number expressed in polar form with magnitude K and angle 0. The Bode plot or diagram of a transfer function can be constructed by combining the transfer functions of following elementary factors. In bode-plot, low-frequency asymptote (that is ω>1/T) cut off at 0 decibels (dB) line where ω=1/T, that is the frequency called corner frequency or break point.
At times, the magnitude of a transfer function is referred to as gain and the corresponding plot as a gain plot. The magnitude of the transfer function is expressed in decibels (dB), the phase in degrees and the common parameter of frequency is plotted on a logarithmic scale in radians.
