Abstract: This paper introduces a low-power multi-channel data acquisition and processing system based on DSP and CPLD. The whole system is composed of DSP and CPLD to dynamically set the A/D sampling...
I want to implement a bandpass filter from 300Hz to 4000Hz using C language, but I don't know how to do it and how to process it so that I know the data corresponds to 300hz, 4000hz....
1. What is Kirchhoff's law? Kirchhoff's law includes current law and voltage law. Current law: In a lumped circuit, at any time, for any node, the algebraic sum of all branch currents flowing out of t...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
As a wireless broadband metropolitan area network standard, WiMAX technology has greater advantages than previous 3.5GHz MMDS products in terms of non-line-of-sight transmission and spectrum utiliz...[Details]
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]

When the so-called "copycat phones" that flood the domestic mobile phone market move towards large screens, stereo amplifiers, touch controls, and even GPS navigation and mobile TV, the homogeneity...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
The capacity of a battery depends on the amount of charge and discharge, in addition to some factors of the battery itself. Obviously, if the charge and discharge of the battery can be recorded all...[Details]
The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[Details]
The automotive power electronics market has grown rapidly as comfort and active safety features become more common. As traditional mechanical functions shift to electronic applications, the demand ...[Details]
