I wrote a PAL interlaced display module on FPGA, using a 50HZ frame rate, generating composite blanking and composite synchronization control signals for odd and even fields, and sent them to DAV7123 ...
I am using XC6SLX9 chip, there is such a line in UCF: NET "A0SD"LOC = P33|PULLUP;This NET is used for the SDA pin of I2C, which usually needs to be pulled up, so it is written like this.But when MAPPI...
I have just started working in the electronic audio industry. Although I know some electronic principles, I am not proficient enough, especially circuit diagrams. I want to read some books in my spare...

As medical equipment develops towards intelligence, miniaturization, serialization, digitization, and multi-functions, the logic control devices in medical equipment have also evolved from medium- a...[Details]
The particularity of portable medical devices determines that they should be user-friendly, must work in a sterile environment, and occupy little space and consume low energy.
At the same time, por...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
Wireless personal area networks (or WPANs) are particularly useful for sensing, monitoring, and control applications. Cost-effective WPANs have the unique potential to implement wireless connectivi...[Details]
This article first briefly introduces the working principles of current mode and voltage mode and their respective advantages and disadvantages; then discusses the ideal voltage mode using output c...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pres...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
