DDS (Direct Digital Synthesis) is a method to produce analog waves using digital techniques. Analog waves can be sine waves, square waves, triangular waves, or others. This research used SimulIDE ...

In this project, the Arduino Uno is configured as a square wave generator with user-selectable control of the frequency and duty cycle.

32-bit I2S with ATmega328P, 1 kHz sine wave, fs 192 kHz, level adjustable from 0 to -110 dB in 16 steps ...

The sine wave generator circuit may be applied in test equipments such as audio voltmeters and audio power indicator. The amplitude of the sine wave is allowed to be varied by this circuit.

Capable of generating sine, triangle, and square waves up to 10MHz with its all-digital circuitry, it’s a piece of gear that’s well worth the $30 USD or so it should cost to build your own ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially ...
