##

To generate a desired output frequency from a given waveform:

- Count the number of samples per period of your waveform
- Calculate the necessary update rate of your device based on this formula:

*Update Rate* =

*Output Frequency* *

*# of Samples per Period***Note: ** If the required update rate is above your device's specification, we will need to modify the waveform, use a faster device, or choose a lower frequency signal to generate.

To generate a desired output frequency with a given update rate:

- Calculate the number of samples for each period based on this formula:

*# of Samples per Period* = *Update Rate* / *Output Frequency*

- Create a waveform of the desired signal with the correct number of samples per period

**Note:** You need to have more than 2 samples per period based on Nyquist Theorem.

### Additional Information

In general, this is the formula for calculating the frequency of the analog signal being output:

*Output Frequency* =

*Update Rate* /

* # of Samples per Period***Note:** Based on

Nyquist Theorem , the quality of the signal is significantly improved by having at least 10 samples per period
