Function Generator
A function generator having a wide tuning range is shown in
Figure 9. The adjustment range, in excess of 1,000,000/1, is
accomplished by a single potentiometer. Three operational
amplifiers are utilized: a CA3160 as a voltage follower, a
CA3080 as a high speed comparator, and a second
