RING MODULATION
“ R i n g m o d u l a t i o n” i n a n a l o g c i r c u i t s i s
accomplished by arranging diodes in a circle or
ring, giving rise to the term, “ring modulator.” The
result is a sound rich in overtones and typically
having somewhat of a bell-like or metallic quality.
Because of this, the sound is sometimes called a
“Klang tone.”
