c语言写了一个简单的正弦波函数

#include<stdio.h>

#include <stdlib.h>

#include<math.h>

#define FQ 1000

#define AM 1000

#define PI 3.14

int main()

{

FILE *stream;

int i=0,j=0;

double value=0,bb=0;

short gg[1000];

stream=fopen("sine_wave.raw","wb");

value=(2*PI/8);

for(i=0;i<1000;i++)

{

bb=AM*sin(value*i);

gg[i]=(short)bb;

//fprintf(stream,"%d/n",gg);

}

fwrite(gg, 2, 1000,stream);

fclose(stream);

return;

}
