摘　　要：本文介绍了一种软件实现生物电等低频信号实时FFT的有效方法,并对96汇编语言环境下基4算法的实现、旋转因子的计算及程序编制的要点等进行了详细说明。经测试得知,该方法在精度、速度方面均可满足一般工程要求,亦具有调式简单、使用方便的特点,因而实用性较强。This paper describes an effeative method for realizing real-time FFT of btoelectric current signal by using Intel 8096 16-bit single-chip micro computer. Solution of problems of base-4 FFT with assemble language and butterfly computation as well as the main points of programming are introduced in some detail, This method meets the requirement of the signal in precision and speed, and can also be used in other fields for its simplicity and convenience.
