Which of the statement is correct with regard to the bandwidth of the control loop system:

• A. in systems where the low frequency magnitude in 0 db on the bode diagram, the bandwidth is measured at the -3 db frequency
• B. the bandwidth is the measurement of the accuracy of the closed loop system
• C. the stability is proportional to the bandwidth
• D. the system with larger bandwidth provides slower step response and lower fidelity ramp response
