Introduction
AD8302 is a monolithic integrated circuit for RF/IF amplitude and phase measurement from ADI. It is mainly composed of two precisely matched broadband logarithmic det...[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]
MIPS Technologies Inc. has introduced the CI10084tg, a next-generation global positioning system (GPS) RF tuner IP solution. The silicon-proven, integrated low-noise RF front end for GPS receivers...[Details]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communication technology since the advent of digital communications. Many new wir...[Details]
Abstract:
QT1101 is a QTouch charge transfer (QT) device, a complete digital controller that can detect signals when approaching or touching up to 10 independent keys. It can be widely used i...[Details]
Focus shift problem
Visible light and infrared light have different wavelengths, so the imaging focus is not on the same plane, which results in a clear image under visible light condition...[Details]
CVC5.0 (CSR recently announced the fifth generation of clear voice capture technology) is the only solution on the market that provides advanced audio enhancement and noise suppression to both the ...[Details]
1 Introduction
Digital video is the use of video capture devices such as cameras to collect external image information and digitize the image information, and then record it to storage med...[Details]
With the development of the electronics and data industries and the promotion of distributed power supply systems in recent years, the application of DC-DC converters has become more and more wides...[Details]
The dual-field-of-view infrared optical system can simultaneously provide two images with different magnifications and fields of view. The large field of view in the system has a lower resolution a...[Details]
