[b]When designers think of passive components, they think of the manufacturing tolerances of inductors and capacitors, which are typically ± 20% or ± 10%. This is true in theory, but not in practice. ...
Now I am applying for a test development board to do some basic experiments. I hope the application will be successful. I hope you can help me a lot during the application process!!...
Recently, I saw an article by QORVO mentioning that there are two mainstream ways to implement 3D Touch. The first is the "capacitive touch + force sensor" mode. In this mode, capacitive touch is resp...

UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[Details]
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
Although improper medical device product design is not always associated with medical device-related errors. Studies of users have shown that lack of adequate training accounts for 70% to 90% of suc...[Details]
This article discusses how to use an ultra-low-power RF transceiver chip from Zarlink Semiconductor for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices to achiev...[Details]
Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]
For more than 10 years, analog-to-digital converters (ADCs) have been widely used in industrial process control, medical instruments, communication systems, radar and other products as a booster of in...[Details]
In some warehousing management, manufacturing, meteorological observation, scientific research and daily life, the requirements for temperature and humidity are common. For example, the "Interim Pr...[Details]
This summary will introduce the transmitter characteristic test of TD terminal products - uplink power control. According to the 3GPP TS34.122 standard, UE uplink power control is divided into uplink ...[Details]
To ensure the success of China's TD-SCDMA network commercialization, operators and equipment suppliers need to conduct a large number of tests on networked equipment, among which RF testing is...[Details]
Today, as network technology becomes more and more popular, industrial field instruments, data acquisition and control equipment are becoming more and more networked, and the combination of industr...[Details]

At present, the analysis of intra-pulse signals in pulse radar has always been a hot topic and difficulty in research. How to measure the intra-pulse carrier frequency more ...[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]
Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[Details]
A correct circuit design cannot be manufactured 100% correctly when it is taken to the factory for manufacturing. It will always be affected by various uncertainties, such as deviations in manufact...[Details]
