In the derivation of expression for peak percent overshoot,
, Which one the following conditions is NOT required? -
In the following circuit , the comparator output in log: "I" if V1 > V2 and is logic "0" otherwise. The D/A conversion is done as per the relations VDAC =
2n-2 Volts, where b3 (MSB), b2, b1 and b0 (LSB) are the counter outputs. The counter starts from the clear state
The magnitude of the error between VDAC and Vin at steady state in volts is -
The signal flow graph of a system is shown below:
The state variable representation of the system can be -
