As part of filter design, simulation, and evaluation, a Bode plot is a basic tool for visualizing a filter’s output for a harmonic input. Keep your circuits as clean as the air in your house with a bandpass filter.įilters are critical circuits for any engineer to understand, and they have simple mathematical representations that help designers visualize their functionality.
Every filter, linear amplifier, impedance matching network, and other reactive LTI circuits will have a transfer function.īode plots are one way to visualize the magnitude and phase of a transfer function for one of these circuits.Ī bandpass filter for some circuits will start to look like a low-pass filter or a high-pass filter, and this behavior can be seen in a Bode plot.
