01 ADC Quantization Error 1. Introduction AD\Test\2024\April\TestATMEGA16.SchDoc Recently, the sampling characteristics of a 10-bit ADC were measured. When the input signal changes very slightly, the quantization error of the ADC greatly affects the sampling results. Even averaging 512 data points cannot eliminate the impact of quantization error. Next, tests were conducted by introducing noise interference … Read more
Let’s take a look at FPGA development projects at international universities. As far as I know, many universities in China do not offer courses related to FPGA, so many students are self-taught. However, self-learning requires certain goals and projects. Today, let’s look at the FPGA project courses offered by Cornell University, an Ivy League school. … Read more
It has been 4 years since the release of the previous generation of Raspberry Pi (RPI4 @2019). The Raspberry Pi 4 even reached a “sky-high price” for a while, becoming a financial product, and there was news earlier this year that there would be no updates. However, the Raspberry Pi has officially announced the information … Read more
