- Figure 1. A variant on Part 1's Figure 2, allowing operation with a supply of up to 20 V
- Figure 2. This all-discrete version (apart from the op-amps) uses a second section to produce an output having a duty cycle close to 50%
- Figure 3. Here the oscillator runs 16 times faster than the output frequency. Dividing the pulse rate down using a twisted- ring counter with resistors on its 8 outputs gives a stepped approximation to a sine wave
- Figure 5. A suitable output filter for adding to Figure 3, and the resulting spectrum
