UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]

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]

A ventilator is an instrument that can replace or assist a person's respiratory function. It is suitable for artificial respiration of patients with respiratory failure or even respiratory arrest. I...[Details]

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]

Implantable Cardivoerter Defibrillators (ICDs) have been in common use for several years. ICDs apply a high voltage pulse between two electrodes connected to the heart, which detects cardiac fibrillat...[Details]

Preface Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[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]

The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]

Engineers who are new to wireless design and wireless product development need to master the basics of RF measurement . In many cases, this process is to enable engineers who have been engag...[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]

introduction With the rapid development of my country's aviation industry, various new aircraft and control equipment have been successfully developed. Some previous measurement and control eq...[Details]

Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[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]
