When purchasing a digital camera, I believe many people will feel overwhelmed by the complicated parameters of the digital camera. Due to the rapid development of digital imaging technology, even those who often pay attention to this industry are often confused about some new technologies. Now let's talk about the definition of the main technical indicators on th

I. Overview of digital signal processing 1. Digital Signal (1) signal: a signal is a carrier for carrying information. Without information, the signal will be meaningless. (2) digital signals: Signals processed by computers 1) Representation: X [N], which is a vertical line with a circle on the top. 2) digital signals

The way to make digital in the future--Siemens ' digital experienceSince ancient times, with "abundance" reputation of Chengdu is a good place to enjoy the ease of life. Ease of life may be a good friend invited to play a game of mahjong, or small groups in the narrow alley of the shadow staggered between a cup of tea. However, in addition to ease, Chengdu has also been changing, the national "West developm

Summary of simple digital clock designIn the information age, the concept of time is deeply rooted, so mastering the design of digital clock has certain epoch significance, and using Multisim to design digital clock for discrete components can greatly improve the quality of personal digital circuits.The design idea is

In the design of electronic system, in order to avoid detours and save time, we should fully consider and meet the requirements of anti-jammingAfter the design is completed, the remedial measures for anti-jamming are carried out. There are three basic factors that form interference:(1) The interference source, which is the component, device or signal that produces the disturbance, is described in mathematical language as follows: DU/DT, di/dt large landSide is the source of interference. Such as
