1. The difference between AC coupling and DC recovery: In DC coupling, the real measured signal is displayed on the screen. In AC coupling, the input signal is coupled through a capacitor before enter...
Signal integrity analysis is critical at 130nm and below. The impact of crosstalk on latency must be considered, as well as the potential for functional failures due to noise jitter hitting nets that ...
ActiveSync is gone in Vista, and it has become Mobile Device Center. I used to use DEVICETODESKTOP in ADOFILTR to transfer CDB data, but what should I do now?...
Platform: pxa270+wce5.0 I want to transplant T9 input method, but it is not loaded. I think it is because the registry is not set correctly. I added the following settings in platform.reg: [HKEY_CURRE...
We have a product based on STM32L152RCT6. Its function is very simple, which is to collect sensor data regularly, do some simple calculations, and then send it out through the serial port. However, th...
Emergency hand-held lamps powered by 6V maintenance-free batteries are widely used in rural areas. The charger used is a transformer step-down and single diode half-wave rectifier, and the charging...[Details]
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
