1. It is closely related with the delta modulation ( see above ). 2. The first step in a delta-sigma modulation is delta modulation . 3. A DSD recorder uses sigma-delta modulation . 4. Modern converter designs based on sigma-delta modulation may become unstable in overload conditions. 5. Historically, state-of-the-art ADCs were based around sigma-delta modulation designs. 6. Derived forms of delta modulation are continuously variable slope delta modulation, delta-sigma modulation, and differential modulation. 7. Derived forms of delta modulation are continuously variable slope delta modulation , delta-sigma modulation, and differential modulation. 8. In delta modulation the change in the signal ( its delta ) is encoded, rather than the absolute value. 9. The results showed no significant effect on mood suggesting that delta modulation might not participate in the regulation of mood in humans. 10. Adaptive delta modulation or [ continuously variable slope delta modulation ] ( CVSD ) is a modification of DM in which the step size is not fixed.
