A government official said, “Currently, the traffic signals installed along the roads have a fixed signal timer but with the Japanese technology, signals will automatically change according to the number of vehicles along the road.” Which of the following could be the reason for the statement? I: The installation of smart signals will reduce the waiting time at signals and junctions. II: The installation of smart signals will solve the traffic woes in the city. III: The technology will be an integrated traffic management center that will ease congestion in the city.
Which of the following statements is/are correct? 1. A continuous-time system is a system in which, continuous-time input signals are applied, resulting in continuous-time output signals. 2. A system is said to be linear if it follows the superposition theorem. 3. A system is said to be non-linear if it follows the superposition theorem.
Consider a control unit generating the control signals. These control signals are divided into five mutually exclusive groups as shown below: Groups  G1  G1  G1  G1  G1 Control  Signals   3  7  10  12  2 How many bits are saved using the Vertical Micro-programmed instead of Horizontal Micro-programmed control unit?
Improve the bracketed part of the sentence. The duos network was (made to learn identify) true signals using previously vetted signals; they then studied the weaker signals.
In MS Excel, what is function inside another function called? A. Round Function B. Sandwich function C. Switch function D. Nested function 
Periodic signals are different in case of continuous time and discrete time signals.
A first-order low-pass filter of time constant T is excited with different input signals (with zero initial conditions up to t = 0). Match the excitation signals X, V, Z with the corresponding time responses for t ≥ 0:
Match List-I with List-II and select the correct answer:
Assertion (A): It is observed that step function is first derivative of a ramp function and impulse function is first derivative of a step function. Reason (R): From the derived time response expression it is concluded that the output time response also follows the same sequence as that of input functions.
A statement is given followed by two inferences I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given inferences, if any, follow from the given statement? Statement: Smart signals that operate on traffic rate rather than a fixed timer are to be installed in City A. Inferences: I. The wait time at the traffic signals will significantly reduce. II. Number of accidents in City A will increase.
Consider the following statements: 1. The delay time is the time required to reach 50% of the final value in the first time. 2. The rise time is the time required for the response to rise from 10% to 90% of its final value for underdamped systems. 3. The rise time is the time required for the response to rise from 0 to 100% for the underdamped systems. Which of these statements are correct?
