PT2394/2395是由台湾普城技术公司设计的一种新型CMOS数字处理回响IC,适用于卡拉OK机,收录音机,录像机及电子琴。在功能上可与三菱公司的M50195P相媲美。PT2394/2395的输入信号以A—D(模—数)方式转换成数字信号,储存在记忆DRAM(动态随机存储器)芯片上,经延时后,数字信号由记忆芯片读出,再以D—A(数—模)方式转换成模拟信号。比传统的BBD(斗链式电荷耦合)器件噪声低、失真小、信/噪
PT2394 / 2395 is a new type of CMOS digital processing reverberation IC designed by Pucheng Technology Co., Ltd. of Taiwan. It is suitable for karaoke machines, tape recorders, video recorders and keyboards. Functionally comparable with Mitsubishi M50195P. The input signal of PT2394 / 2395 is converted to digital signal by A-D (modulo-number) and stored in memory DRAM chip. After delay, the digital signal is read out by memory chip, A (digital - analog) mode into analog signals. Compared with the traditional BBD (bucket chain charge-coupled device) low noise, distortion, signal / noise
