This tool computes the signal bandwidth from its frequency.

- Enter the fundamental frequency
- Pick the signal type (
**sine, square, triangle or sawtooth**)

The units of the signal bandwidth are the same as that of the signal frequency.

**Examples**

A **sine wave** with a fundamental frequency of **1 GHz** has a bandwidth of **1 GHz**, while a square wave with the same frequency has a bandwidth of **5 GHz**.

**Example Applications**

- Rise Time Calculator – use bandwidth to find the rise time of the signal
- Nyquist Rate Calculator – what’s the sampling rate to avoid aliasing? Once you calculate the bandwidth, use this tool to pick an appropriate oscilloscope or analog-to-digital converter.
- Nyquist Frequency Calculator gives the maximum frequency of the input signal to avoid aliasing.
