- Figure 1. An on/off/on switch gives three gain settings in a non-inverting amplifier stage and does so in a rational order
- Figure 2. Ternary switching over three stages gives 0-26 dB gain in precise 1-dB steps
- Figure 3. An inverting amplifier stage using the same switching principle
- Figure 4. A single attenuation stage with three switchable levels
- Figure 5. Binary switching of gain from 0 to +31 dB, using power-of-2 steps. Again, the theoretical resistor values are much closer to the ideal than their actual 1% tolerances
