<div dir="ltr" align="left"><span><font color="#0000ff" size="2" face="Arial">To answer Quincas's question below: It is relatively
hard to make a sine wave directly without using a self-oscillating filter or a
digital wavetable. It is harder to get superior tracking in a filter than
in a well-designed VCO. Also, it is pretty hard to shape a sine into
anything else, because it has no sharp edges or straight lines. It is very
straightforward to shape triangles or saws into the other waves with rectifiers
and plus-minus amps, which are easy to design.</font></span></div>

<div dir="ltr" align="left"><span><font color="#0000ff" size="2" face="Arial">Also, a sine shaper to get a sine with a THD of about 0.5 to
1.0% is convenient and cheap.</font></span></div><span>

<div>I have another question about the sinewave issue (btw I love my sines,
use them all the time, but only the filters in oscillation give me perfect
sines)</div>
<div>Is there not a way to make a sine core oscillator
and derive the other waves from it? Like a filter with fixed high resonance
for the sine, a comparator for the square etc...</div>
<div>Why doesn't anybody do that?<br><br>Quincas Moreira<span><font color="#0000ff" size="2" face="Arial"> </font></span><span> </span></div></blockquote></span></div>
