A Bode diagram, like the one shown below, helps to quantify how well the output, or feedback (F), follows the command (C) by showing the relationship between A and the frequency of excitation. The frequency is normally expressed in radians/sec.(ω) rather than cycles per second (f). Since ω = 2πf ≈ 6.28 f, it is easy to convert from one to the other. Also, 1/ω, in seconds, is the time constant of a low pass filter with a bandwidth of f. Once we know the bandwidth (ω) of a servo, we know the time constant of the equivalent filter (1/ω) and can thus predict its response to a step input.

What are stepper motors good for?
Positioning – Since steppers move in precise repeatable steps, they excel in applications requiring precise
positioning such as 3D printers, CNC, Camera platforms and X,Y Plotters. Some disk drives also use stepper motors to position the read/write head.
Speed Control – Precise increments of movement also allow for excellent control of rotational speed for
process automation and robotics.
Low Speed Torque - Normal DC motors don't have very much torque at low speeds. A Stepper motor has
maximum torque at low speeds, so they are a good choice for applications requiring low speed with high
precision.

Many users of motion control have heard vendors try to explain certain servo features by using Bode diagrams. A basic understanding of them is necessary in dealing with motion. To begin with, the proper pronunciation is "Bo-dee". Just think of Bo Derek (which isn't hard to do). You'll find other similarities between the two (who am I kidding?) like the number 10, as will be seen.
