Students who focus on "control" competition questions need to understand and master the following knowledge points: Based on the previous competition questions, students who focus on "control" competi...
The stock market is risky, so you need to be cautious when entering the market. That's true. I used to watch my colleagues speculate in funds every day and make a lot of money, so I followed suit. I w...
I recently got a batch of SSM2142SZ chips. I want to build a simple circuit to test the output function. However, the power supply I have can't provide -18V, only 18V. This is a dual power supply. Can...
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]

The rapid development of medical imaging technology continues to promote the progress of modern medicine. CT, MRI, and PET are widely ...[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]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[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]
How can we get the highest performance from an A/D converter? The obvious answer is to use good design and board layout, but there are other techniques that can be used to improve performance. We can ...[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]
The particularity of portable medical devices determines that they should be user-friendly, must work in a sterile environment, and occupy little space and consume low energy.
At the same time, por...[Details]
In response to a series of problems caused by the backwardness of traditional water meters, the Ministry of Construction of China has proposed the requirement of "three meters per household" for ur...[Details]
Safety is the top priority in the production process, especially for dangerous operations. When the high-voltage line is shut down for maintenance, it is necessary to follow the regulations of powe...[Details]
Lithium-ion battery is a widely used rechargeable battery. It has the advantages of high single-cell operating voltage, small size, light weight, high energy density, long cycle life, rapid full ch...[Details]
With the development of the automobile industry, the complexity and information density of automobile information systems are increasing. Displays are no longer just basic centralized instrument di...[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]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pressur...[Details]
