FP + OOP = Haskell. The programming language Haskell adds object-oriented functionality (using a concept
known as
type classes
) to a pure functional programming framework. This paper describes
these extensions and analyzes its accomplishments as well as some problems.
介紹了以PLC為控制單元，變頻器為執(zhí)行單元的控制系統(tǒng)及其在煙支輸送儲(chǔ)存系統(tǒng)中的應(yīng)用，并給出了系統(tǒng)的組成、硬件的配置及具體的實(shí)現(xiàn)方法。關(guān)鍵詞 : PLC 變頻器輸送儲(chǔ)存系統(tǒng)

現(xiàn)代通信系統(tǒng)要求通信距離遠(yuǎn)、通信容量大、傳輸質(zhì)量好。作為其關(guān)鍵技術(shù)之一的調(diào)制解調(diào)技術(shù)一直是人們研究的一
個(gè)重要方向。討論和仿真實(shí)現(xiàn)了基于FPGA的數(shù)字化DPSK調(diào)制解調(diào)系統(tǒng)。用Altera公司的FPGA開發(fā)平臺(tái)Quartus II 3.0實(shí)現(xiàn)了一
個(gè)對(duì)基帶信號(hào)的DPSK調(diào)制解調(diào)系統(tǒng)模型的仿真。
