Formula and methodology
Formula: Bandwidth = fhigh − flow; center frequency = (fhigh + flow)/2.
The calculator treats the entered limits as the edges of one linear frequency interval.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Lower frequency — Hz; minimum 0; maximum 1000000000000
- Upper frequency — Hz; minimum 1.0E-6; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Lower frequency | 20 |
| Upper frequency | 20000 |
Bandwidth = 19,980 Hz; center frequency = 10,010 Hz.
Assumptions and limits
- Both frequencies use hertz and the upper edge is greater than the lower edge.
- The band is represented by linear frequency, not an octave or logarithmic bandwidth.
- Filter shape, roll-off, noise, and signal power are not inferred.
