#Training Camp# Simple Digital Oscilloscope

The principle of a simple digital oscilloscope based on the GD32:








A digital oscilloscope uses its built-in analog-to-digital converter (ADC) to sample the input signal. This is the first crucial step in a digital oscilloscope, involving the conversion of analog signals into digital signals.
















The input voltage signal is first sent to the front-end amplifier through a coupling circuit. The amplifier amplifies the signal to improve the oscilloscope's sensitivity and dynamic range.
Digitization: The amplified signal is converted into a digital signal by the ADC. In this process, the signal is digitized, which determines the accuracy of subsequent processing.
Storage and processing: The digital oscilloscope stores the digital signal in memory and performs necessary processing and analysis, such as performing FFT transformations, averaging, and convolution.
















Signal display: The processed signal is displayed as a waveform on a high-brightness display, intuitively representing the entire testing process.
