-1E^20<>1E^20 Equation constants

Typing Equations If you remember from your high school, the simple equation for a line

is Y=aX+b. You can use the same equation to generate straight lines

with the Equation Editor. Assuming first that p=0, try this:

Ampl(p)=1000

Press [Preview] and see the flat line which runs parallel to the X-axis.

Now, lets give the line some slope by typing:

Ampl(p)=-2*p+2000

Press [Preview] and see that the line slopes down. Pay close atten-

tion to the convention that is used in this equation. You cannot type:

Ampl(p)=-2p+1000, instead use the * (multiply) sign, to avoid a syn-

tax error. Now we'll generate a simple sine waveform. Try this:

Ampl(p)=sin(10)

Press [Preview] and you still get a flat line. The sine of 10 in radians

is correctly shown. You are unable to see the result because the line

on your screen running across the 0 vertical point.

REMEMBER

The equation must be a function of a single variable and

that variable must be directly related to the Horizontal

axis Scale setting.

Now try this:

Ampl(p)=sin(omg*p)

Press [Preview] and there is no waveform for now, but press the

[Adjust] button and the sine appears. To add amplitude (in vertical

points) to your waveform, enter:

Ampl(p)=6000*sin(omg*p)

You should now see a perfect sine waveform with a period of 1000

points. If you want to create 10 sine cycles, multiply p by 10. Try this:
