Graphic PCB wiring digital, analog, power supply, single point grounding anti-interference!

~ 1. Digital, analog, and power supply on the Board: From this figure, we can see that the analog and digital locations are completely separated, and finally each point is connected to the power source, which can prevent the mutual Crosstalk of the ground signal from affecting some sensitive components, as we all know,

C Language Algorithm for Digital Filter Based on moving average method against pulse interference and Its Implementation

In many data collection systems, there are many on-site strong electrical equipment, which is inevitable. The ground will produce sharp pulse interference, which generally lasts for a short period of time and has a large peak value. When performing digital filtering, only arithmetic mean or moving average filtering is used. Although 1/n is processed for pulse interferen

Concepts of digital TV

DTV: digital television refers to the digital technology used to process, compress, encode, and store active images, sounds, and other signals, A television system for receiving and Playing videos. All aspects of the system, including the process from Studio program production, to processing, transmission, storage/transmission, to receiving, displaying, and so on, all adopt

Application of DVBS/S2 in digital TV system VIII (now popular dual tuner application)

television, we call dual tuner. In the case of European digital television, the general single tuner, which supports DVBT/C/S and ATV TV, usually sees two tuner connector. A threaded receive head is used separately for dvbs, and the other non-threaded is for DVBT/C/ATV reception. So, dual tuner can basically be considered as two sets of single tuner, but not simply splicing.Say so much, it is better to loo
