I am working on a switching power supply recently. It can output normally, but the load regulation rate is relatively high. I guess it is due to unstable feedback (two resistors are used for voltage d...
Hey guys, does anyone know how to cancel a certain encryption algorithm supported by openssl, such as: AES128-SHA, AES256-SHA, DES-CBC3-SHA, etc.? I compiled openssl on ubuntu, and after compiling, I ...
My Logitech keyboard does not require special software support (no need to install drivers), and there are some special function keys on it that can be pressed to open the calculator, MediaPlay, incre...
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[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]
As microcontrollers become less expensive and more powerful, electrical designers are finding it more cost-effective to use multiple small controllers in both single-board and multi-board systems. ...[Details]
Overview
Currently, many portable consumer electronic products, such as mobile phones, PDAs, MP3 players, and notebooks, are equipped with display screens. Although the type and size of the di...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]
According to In-Stat/MDR, the number of mobile phones with Bluetooth capabilities will reach at least 300 million by 2005. One of the clear evidences of the increasing adoption of Bluetooth is that...[Details]
1 Introduction
Generally, when transmitting information over short distances through electrical signals, baseband signals can be directly transmitted. However, over long distances, baseban...[Details]
