## Bandwidth Formula

The following formula is used to calculate a bandwidth.

BW = fc / Q

- Where BW is the bandwidth (Hz)
- fc is the resonant frequency (Hz)
- Q is the quality factor

## FAQ

**What is a bandwidth?**

Bandwidth is a rand of frequencies within a certain band of a transmitting signal.

## Bandwidth Example

How to calculate bandwidth?

**First, determine the natural frequency.**Using the calculator linked above, determine the natural frequency. We will assume 25 Hz for this example.

**Next, determine the quality factor.**The quality factor for this example is found to be 5.

**Finally, calculate the bandwidth.**Using the formula above, we find the bandwidth of the system to be 25/5 = 5 Hz.
