The frequency divider refers to distinguish the sound signals of different frequency bands, respectively amplify them, and then send them to the speakers of the corresponding frequency bands for replay. When reproducing high-quality sound…
Abstract: Signal generators based on op amps have low accuracy and poor stability and adjustability. DDS-based signal generators are costly and complex. A design method of multi-channel signal generator based on FPGA+PWM is pr…
One of the biggest advantages of FPGAs is that you can solve the toughest mathematical transfer functions with their embedded DSP blocks. The polynomial approximation is a good way to do this.
Because of its fle…
Located in Finland in Northern Europe, the mobile phone overlord Nokia was born. At its peak, Nokia once occupied more than 40% of the global market and sold more than 1 billion mobi…
If you are an engineer working on field-programmable gate arrays (FPGAs), you should be aware that the efficient operation of these devices requires an optimized power supply sequence. Using discrete components to meet these specific power req…
The solution integrates multiple switching regulators, LDOs, and supervisor/watchdog timers on a single-chip IC

It can be said that if you do 3D printing now, you basically don’t make money. It may be difficult to make money in the next year or two. However, why do we still enjoy layout 3D printing? I think that not making money now does not mean that we cannot make money in the future. Now e…
Abstract : Combining the advantages of ARM's flexible operation and FPGA real-time processing, it is proposed to use ARM + FPGA structure to drive high-resolution RGB888 LCD display. The ARM interface is rich and the operat…
