问题描述
嗨...
我已经制定了一个正弦波代码:
private double DegreeToRadian( double angle)
{
return Math.PI * angle / int .Parse(textBox3.Text);
}
私有 void 绘制( double N)
{
int Yoffset = panel1.Height / 2 跨度>;
Graphics G = panel1.CreateGraphics();
Pen P = new 笔(Color.Yellow, 1 .5f);
float x1,y1;
for ( double X = 0 ; X < = 360 ; X ++)
{
x1 = ( float )X;
y1 = Yoffset +(( float )Math.Sin(DegreeToRadian(X * N))* int .Parse(textBox2.Text));
G.DrawRectangle(P,x1,y1,.5f,.5f);
}
P.Dispose();
}
然后Button_Click:
绘制( int .Parse(textBox1.Text));
现在我想...我如何以赫兹显示频率?
解决方案
Hi ...
I've drawn up a code of sine wave :
private double DegreeToRadian(double angle) { return Math.PI * angle / int.Parse(textBox3.Text); } private void Draw(double N) { int Yoffset = panel1.Height / 2; Graphics G = panel1.CreateGraphics(); Pen P = new Pen(Color.Yellow, 1.5f); float x1, y1; for (double X = 0; X <= 360; X++) { x1 = (float)X; y1 = Yoffset + ((float)Math.Sin(DegreeToRadian(X * N)) * int.Parse(textBox2.Text)); G.DrawRectangle(P, x1, y1, .5f, .5f); } P.Dispose(); }
Then Button_Click :
Draw(int.Parse(textBox1.Text));
Now I want ... How do I display the frequency in hertz?
