Hello Melanie,

Melanie>>If you create a sinewave from your 10 or 12-bit component, and you magnify the edge, it'll still have little square-shaped teeth marks in it. Those teeth marks will have sharp square edges... and square edges give high frequency harmonics... so your sine-wave (especially ladder network created types) will be as pure as the driven slush.<<

You are correct...But some folks like the el-spike-o sine wave. <g>.

then you have the problem of the negative 5 volts too. Thus your signwave is actually betwen 0 and 5 volts. Oh well. I figured by the time a person wastes creating such a wave, they might as well turn a magnet within a coil of wire <g>.

But I also have to admit, I enjoy building things as such for the experience and practice.
