In the following the transfer function , frequency response , Nyquist plot and the Bode diagram for some important elements will be derived and shown.

- The proportional element (P element)
- The integrator (I element)
- The derivative element (D element)
- The 1st-order lag element (PT
_{1}element) - The proportional plus derivative element (PD element)
- The derivative lag element (DT
_{1}element) - The 2nd-order lag element (PT
_{2}element and PT_{2}S element) - Bandwidth of a system
- Example for the construction of a Bode plot
