The sampling rate is a measure of how often a waveform is sampled. If it is sampled once every 10 seconds then the sampling rate is 0.1 Hz.

To calculate the sampling rate enter:

- Number of samples (
**N**)_{S} - Time period over which the samples were collected (
**T**)_{S}

**Formula**

**Sampling rate = N _{S}/T_{S}**

**Example Calculation**

If 1000 samples are collected over a time period of 5 seconds, the sampling rate is 200 samples per second.

An important specification for an Analog-to-digital converter is its sampling rate. The AD9670 for instance, has a maximum sampling rate of 125*10^{6} samples per second.
