The reception of FM broadcasts has been a hot topic in recent years, especially last year. This is because FM broadcasts have better sound quality, higher fidelity, stronger anti-interference, and richer programs than AM broadcasts. The most critical It is low cost, although di

Electronic enthusiasts or maintenance personnel sometimes need a single-end low-voltage DC power supply and can output high-power portable amplifiers when they go out for advertising or playing music, and the general portable recorders often play very little. Here is a descrip

At present, the popularity of home computers has swept across the country, especially the rich, novel and unique functions of multimedia computers have attracted a large number of fans. Newspapers and books have also developed and published many computer-related columns and ar

Due to the reliable performance and reasonable price of the TDWT series amplifiers, they are widely used in the current cable TV network transmission. After several years of operation, the author summarizes the following two treatment methods for the TDWT series amplifiers, and
