目前,在盒式磁带录音机上已广泛使用了自动选曲电路。其选曲方式分为两种,即前后一曲自动节目搜索系统(日本夏普公司称之为APSS系统),和前后多曲自动节目定位装置(日本夏普公司称之为APLD装置),也称电脑选曲。另外还有一种自动节目暂停系统(夏普公司称之为APPS系统)。APLD和APPS系统的工作原理都是在APSS系统的基础上增加了记忆、存储部件而发展出来的。基本工作原理相似。本文向读者介绍一种新颖的盒式磁带录音机自动选曲电路,并推荐一种新颖的自
At present, automatic music selection circuits have been widely used on cassette tape recorders. The song selection is divided into two types, namely, before and after an automatic program search system (Japan’s Sharp company called APSS system), and before and after the song automatic program positioning device (Japan’s Sharp company called APLD device), also known as computer Selected songs. There is also an automatic program to suspend the system (Sharp company called APPS system). APLD and APPS systems work on the basis of the APSS system to increase the memory, storage components and developed. The basic working principle is similar. This article introduces readers to a novel automatic cassette selection circuit tape recorder and recommends a novel
