- Figure 1. A2 feedback and TDA7052A's antilog VC gain control create a ~300-mW, 5-octave linear-in-pitch VCO. More or less…

- Figure 3. R4 works with the 14 kΩ internal Vc bias to make a 5:1 voltage divider, converting 0 to 2 V into 1±0.2 V
- Figure 4. VC's 0 to 2 V antilog gain control span programs A1 pin 4 from 0.8 V to 1.2 V for 1x to 32x gain and FOSC = 100 HzA1gain = 100 Hz(5.66Vc) = 100 to 3200 Hz
