低频信号实时FFT的PC汇编程序设计

The Method about Real-Time FFT of Low Frequency Signal Based on PC MASM Language

本文介绍了一种可以直接利用通用PC机进行低频信号实时FFT的有效方法,给出了具体的汇编语言源程序,并针对其实现难点进行了详细的说明。经测试得知,这种方法在精度、速度方面均可满足一般工程需要,亦具有调试简单、使用方便的特点,因而实用性较强。

This paper describes a effective way of designing the low frequency real-time FFT implemented in MASM language on PC. Some difficult points are explained in detail. The paper also offers the program Which makes a considerable speed advantage by more than twenty times over the program written in hish-level languages.
