Sketching the nyquist plot based on the bode plots for the mentioned systems require a certain understanding of bode plots explained in detail.
In reality, Bode plots are a collection of graphs that display a system's frequency response. This system might be any system (not simply a circuit!) that changes its behavior when its frequency (cycles per second) changes.
Frequency Response simply describes how our system will alter in response to a specific input frequency. This collection of notes will be referred to as our input frequency.
Bode charts often have two graphs. We'll refer to one as the magnitude plot and the other as the phase angle plot.
We'll need something initially called a transfer function. Typically represented as H(s) or H(j). A transfer function often equates to the ratio of the output to the input.
