Dual-slope integration type Analog-to-Digital converters provide 1. Higher speeds compared to all other types of A/D converters. 2. Very good accuracy without putting extreme requirement on component stability. 3. Good rejection of power supply hum. 4. Poor resolution compared to all other types of A/D converters for the same number of bits. Which of these statements are correct? Consider the following statements regarding the circuit given in the figure, where the output voltage is constant; 1. V in > the Voltage at which the Zener breaks down. 2. I L < the difference between I and I z the current at which the Zener breaks down. 3. R s < the Zener normal resistance. Of these statements Which one of the following system is nonlinear? [y(t) = output; x(t) = input] In the radar guidance of missiles, the technique makes use of two separate tracking beams, one tracking the missile and the other tracking the target. The missile is commanded to follow a trajectory based on the data from the two tracking radar beams. It is For type 1 system the velocity lag error is
