# Bode Plot

Bode plots are graphical representations of the frequency response.

- We need two plots: one for $∣H(jω)∣$ in “decibels” (dB) vs log10(ω) and one for $∠H(iω)$ vs $g_{10}(ω)$
- The aforementioned plots are called the “magnitude” and “phase” curves respectively.

Definition 1: Decibels

$∣H(jω)∣$ in decibels is $20g_{10}(∣H(jω)∣)$.
