Bode Plots

Bode plots are graphical representations of the frequency response of a system. There are two types of plots: one with a magnitude response and one with a phase response.

Magnitude response: It represents the Gain response of the system as a function frequency.

Phase response

It represents the frequency-dependent phase shift of the system output signal compared to its input signal


Sinusoidal Steady State Analysis – Electric circuits

In steady state (the fully charged state of the cap), current through the capacitor becomes zero. The sinusoidal steady-state analysis is a key technique in electrical engineering, specifically used to investigate how electric circuits respond to sinusoidal AC (alternating current) signals. This method simplifies the intricate details involved in time-varying AC circuits by representing voltages and currents as phasors—complex quantities that succinctly convey both amplitude and phase information.
