SRPP(Shunt Regulated Pust-Pull)电路,即并联调整推挽电路是一款线性接近理想,而失真度、动态以及输出阻抗都比一般甲类放大电路更加好的优秀电路。该电路最早使用在视频领域,所以频率响应非常宽,现在用于音频领域,确有杀鸡用牛刀的感觉。笔者早在1992年春看到贵体翔先生在《实用电子文摘》上介绍日本的须贺一男用该电路做输入兼推动的混合型胆石机,频响宽达360kHz等指标后,曾立志今后一定要玩一玩该电路。同年12月时,再看到何绍和先生在《无线电与电视》上介绍该电路时,再也仰制不住兴奋。从1993年春到1996年春这三年
The Shunt Regulated Pust-Pull (SRPP) circuit, a shunt regulated push-pull circuit, is an excellent circuit with linearity near ideal and better distortion, dynamic, and output impedance than a typical Class A amplifier. The earliest use of the circuit in the field of video, so the frequency response is very wide, now used in the field of audio, does have the feeling of chickens with chops. As early as the spring of 1992, I saw you Mr. Xiang in the “Practical Electronic Digest” introduced Japan’s Suga a male input and push the circuit to do with mixed gallstones, frequency response up to 360kHz and other indicators, had determined in the future certain Have fun playing this circuit. In the same year in December of the same year, when I saw Mr. Ho Shao He introduced the circuit in “Radio and Television,” she could no longer afford to be excited. From the spring of 1993 to the spring of 1996 these three years
