| Abstract: | n this paper,some methods of the hot A/D conversion were offend. By analysing the Fast Data Acqwisition,it was pointed out that the data transmission is the key to affect the rate of the system. Some other metheds are also introduce by which the data can be transmited rapidly into the memory.The advantages and disadvantages of each method are discussed and its appalicability is deseribed separately. |
