convert analog scanner to digital

MCU is a typical digital system, digital system can only be a digital signal processing input, its output signal is also digital. However, many quantities in industry or life are analog, which can be converted to the corresponding voltage, current and other

sampling points will lead to poor Video performance. Inaccurate color information may be due to impedance mismatch, reflection and excessive instantaneous disturbance on the RGB three-color line. Inaccurate sampling may be caused by clock jitter, phase, frequency drift, and other problems.The settings of the analog screen are more complex than those of the digital screen. End users must set the total numbe

It's not that the two of them have a long angle on their heads. It's very strange. You need to understand why you need to separate them. First, let me tell a story.The business building of our company is located on the third floor, the second floor is simulated, and the third floor is

Based on different video switching modes, video matrices are divided into analog matrices and digital matrices. Simulation matrix: The video switching is completed at the analog video layer. Signal switching is mainly implemented by using single-chip microcomputer or more complex chip control analog switches. Number Ma

quantity as the standard of conversion, the most common reference standard is the maximum convertible signal size. The output number indicates the size of the input signal relative to the reference signal. Classification of ADC There are many kinds of analog-to-digital converters, which can be divided into indirect ADC and direct ADC according to the working principle. The indirect ADC is to

Before learning a number of modes of electricity, A/D conversion of the knowledge, also Baidu a lot of information is difficult to understand. Forget, first self-righteous, and so on after the study of specialized courses and then again. (You must learn to go home in winter vacation.) Well, that's what it's all about. Reading so much information, the sense of A/D conversion is the voltage (or other analog: such as pressure, image, etc.) into the

The STM32 DAC module ( digital/Analog Conversion module ) is a 12-bit digital input, voltage-output DAC. The DAC can be configured in either 8-bit or 12-bit mode, or it can be used with a DMA controller. When the DAC is operating in 12-bit mode, the data can be left-justified or right-aligned. The DAC module has 2 output channels with a separate converter for eac

The conversion current that implements the digital signal to the analog signal is called a digital-analog (d/a) converter, referred to as the DAC (Digital-analog convert).At present, th
