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]

Microelectromechanical systems (MEMS) are gradually entering the consumer, industrial, medical, automotive and computer application markets. Moreover, we cannot ignore their steady progress in the ins...[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]

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]

Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]

introduction Mobile phones, MP3 players, hard disk players, digital cameras, PDAs and other devices are all controlled by navigation keys. Currently, the more popular navigation key contro...[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]

introduction In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]

In the issue of ensuring the safety of drivers and pedestrians, the proportion of electronic technology has increased. According to the survey, 80% to 90% of traffic accidents are caused by driver...[Details]

Industrial control often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]

introduction Every friend who has been in contact with PC since the 286 era must have deeply experienced the convenience brought to our lives and work by the leaps and bounds of comput...[Details]
