Низкочастотный цифровой DDS функция генератор сигналов шум выход квадратный пилообразный ECG инструмент ЖК-дисплей Регулируемый Синусоидальная волна DIY

Descriptions:
This is a function (waveform) signal generator.
It can produce some special periodic time function waveforms, such as sine wave, square wave, triangle wave, saw tooth and pulse wave, etc.
The frequency range can range from a few microhertz to a few tens of megahertz.
The offset amplitude of DDS signal can be adjusted by two potentiometers.
Signal generators have a wide range of applications in circuit testing and equipment testing.
It is also used in learning and design circuits.
