What is a DAC? When we want to convert digital signals into analog signals, we need a Digital-to-Analog Converter, also known as a DAC. A DAC is a circuit chip that converts digital signals into analog signals. It is an essential component in modern electronic devices, widely used in digital audio equipment, control systems, instrumentation, … Read more
AuthorForum Account:Su ZifangxuanRecently, I have been learning about USB communication and thought about whether the Ai8051, which has USB and a 40MHz main frequency, could simulate the logic analyzer of the Cypress microcontroller that runs at 24MHz found online.I tried it, and it actually works. Although the performance is not as good, it can run.Here … Read more

Used to evaluate level compatibility, current driving capability, etc. when connected to MCU or FPGA: Parameter Description Condition Min Typical Max Unit Interpretation VIH High-level input threshold – 0.8×OVDD – – V Digital input … Read more
The sampling rate refers to the speed at which an Analog-to-Digital Converter (ADC) samples the analog input, or the speed at which a Digital-to-Analog Converter (DAC) outputs the analog signal. This rate is typically provided by the external clock rate to these converters. However, modern ADCs and DACs often have an internal Phase-Locked Loop (PLL) … Read more
Colleagues, after receiving the book, please confirm receipt in the small shop, thank you! To order the book, you can click the image below to go to the pre-sale notification for ordering. Digital Signal Processing (DSP) is performed on the collected time-domain signals to obtain their frequency-domain results. When signals are transformed from the time … Read more
When talking about oscilloscopes, one cannot help but recall the time spent testing at Samsung.The first version of the product’s PCB was followed by time spent in the lab, racing against product cycles, with continuous validation and testing during that period.It has been a long time since I last tested; I feel a bit nostalgic … Read more
Before learning how to use an oscilloscope to reduce noise, let’s first understand how noise in oscilloscopes arises. Many people who have just transitioned from analog oscilloscopes to digital oscilloscopes may complain that the waveforms measured by their new oscilloscope are not as clear as those from their old analog oscilloscope, even doubting whether their … Read more
Digital Signal Processing (DSP) is applied to the collected time-domain signals to obtain their frequency-domain results. When a signal is transformed from the time domain to the frequency domain, there are specific DSP terminologies, and these terms have important mathematical relationships with each other. Are you clear about them? The following are the DSP terminologies. … Read more
