频率合成技术在现代电子技术中具有重要的地位。在通信、雷达和导航等设备中，它可以作为干扰信号发生器；在测试设备中，可作为标准信号源，因此频率合成器被人们称为许多电子系统的“心脏”。直接数字频率合成（DDS——Digital Direct Frequency Synthesis）技术是一种全新的频率合成方法，是频率合成技术的一次革命。本文主要分析了DDS的基本原理及其输出频谱特点，并采用VHDL语言在FPGA上实现。对于DDS的输出频谱，一个较大的缺点是：输出杂散较大 ...

this program uses an impulse train, takes formant frequencies and filters them. output signal is synthesized sound.
commented part ,controls time=d, sampling frequency=fs
normal frequency=f
and bits=n, then synhesizes the output sound
