Finally, sine oscillators using CFA also have been introduced, a sine oscillation circuit using two CFA~ s has been presented, which can realize independence adjustment about frequency and condition of oscillation. 最后,对基于CFA的正弦波振荡电路作了阐述,并用两个CFA-设计了一种正弦波振荡器,该电路能实现振荡频率和振荡条件的独立调节。
The development history and present situation of oscillation technique of CCM mould are introduced, and the forms of the sine and non-sine oscillation analyzed. 介绍了连铸机结晶器振动技术的发展历史和现状,分析了正弦和非正弦振动的形式。
