UC3846 uses sampling resistor to detect the primary center tap current to control the duty cycle. Now it is open loop. After the feedback input voltage is given, when the input voltage rises, the duty...
Haha, although this is a weak question, I'd like to share with you guys. Generally, when a car passes by, the alarm will sound. A slight vibration will sound the alarm, not to mention a thunderstorm. ...
I would like to ask a question: I use C8051F361 microcontroller, and use P14 and P15 pins to measure the input signal frequency. I give P15 a 1.25 reference voltage. P14 pin is the input signal. But t...
Agilent Technologies recently announced that its China Communications Product Center in Beijing will continue to increase its R&D investment in TD-SCDMA test products. Agilent has made outstanding ach...
The circuit shown in the figure is a three-digit tachometer used to measure low frequency signals with a repetitive time interval of 0.235 to 15 seconds. The tachometer has a speed range of 4 to 255 r...[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]
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]
The small size and low cost of home appliance control boards mean that high-cost materials will not be used in the circuit to solve the electromagnetic interference problem. The interference of hom...[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]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communications since the advent of digital communications. Many new wireless commun...[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]
Siimpel announced that its MEMS-based silicon camera technology, SiimpelFocus SF9x, has been used in Motorola's newly released MING A1600 mobile phone. The MING A1600 is the industry's first mobile...[Details]
Abstract:
Aiming at the problems of repeated design and high cost of existing LED large-screen displays, a modular LED large-screen display is proposed, which can realize flexible configurati...[Details]
This paper introduces the technology and application of optical transceiver modules and digital non-volatile variable resistors in optical communication networks, and focuses on the design and appl...[Details]
1 Introduction
In recent years, with the rapid growth of mobile phones and MP4 video players, it is estimated that the production of mobile phones this year will reach 1 billion units, and...[Details]
1 Introduction
With the rapid development and continuous progress of computer, network communication and Internet technology, embedded systems are widely used in homes and industries. ...[Details]
Agilent Technologies Inc. has announced a new Unlicensed Mobile Access/Generic Access Network (UMA/GAN) test capability on 3GSM that is both extremely affordable and easy to use. The industry's fi...[Details]
