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]

Conventional ECG recorders are one of the main means for doctors to diagnose heart diseases, but they can only record short heartbeats. In many cases, it is difficult to record ECG changes during a...[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]

0 Introduction Metal halide lamp (MHL) as a green lighting source has been widely used in the field of indoor and outdoor lighting. However, when using this green lighting source, the matc...[Details]

In the future, a complete automobile safety system must fully combine gyroscopes, accelerometers, steering wheel and brake pedal position detectors, and tire speed detection systems to accurately ...[Details]

introduction Controller Area Network (CAN) is a bus standard proposed by Bosch of Germany to solve the information communication between automotive electronic control units. With its excel...[Details]

1. What is fading? In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]

Most embedded systems are powered from a 48V backplane. This voltage is typically stepped down to a lower intermediate bus voltage of 24V, 12V, or 5V to power the circuit board racks withi...[Details]

Abstract: By controlling the supply voltage of the radio frequency (RF) power amplifier (PA) in a CDMA/WCDMA cellular phone, the PA efficiency can be improved, heat generation can be reduced, and t...[Details]

Abstract: This paper introduces the controller, interface, display principle and driving method of the handheld computer LCD display based on the SA1110 microprocessor. Combined with the HPC projec...[Details]

Touch sensors have been in widespread use for many years, but recent advances in mixed-signal programmable devices have made capacitive touch sensors a practical, value-added alternative to mechani...[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]

The growing global interest in green power has added new variables to the design of power supplies and power adapters. Designers must not only traditionally consider the design specifications requi...[Details]

Today, the value of electronic components in cars accounts for 15-20% of the total vehicle. In the future, as more safety electronic devices, fuel consumption and fuel emission control electronic s...[Details]
