If you insist: I was looking at my really old RCA IC
data book when I spied an IC for decoded color TV
signals. It uses two balanced (de)modulators fed by a
quadrature oscillator. I couldn't help but wonder what
that might sound like. Then I remembered a project for
a direct-conversion radio receiver that used the same
technique. the article said when heard in stereo
headphones it sounds rad. So I have decided to give it
a try. I'm going to this:
