A. System-delta modulation B. Sigma-delta modulation C. Source-delta modulation D. None of the mentioned
Explanation: In DM, Furthermore, the two integrators at the encoder can be replaced by a single integrator placed before the comparator. This system is known as sigma-delta modulation (SDM ). 7. What is the system function of the integrator that is modeled by the discrete time system?
