Sketch signals given by following equations : 1. x(t) = u(t) - u(t-1) 2. x(t) = δ(t+1) - δ(t-1)
Answer : --- ## **Understanding the Functions** Before sketching, you need to understand two basic functions: ### 1. **Unit Step Function \( u(t) \):** - **What is it?** The unit step function ... - For **impulse functions**, focus on where the spikes occur and whether they are positive or negative. ---...

Define the following ratings of a motor: (i) Horsepower rating (ii) Short-time rating
Answer : (i) **Horsepower rating**: The horsepower rating of a motor refers to the maximum power output that the motor can deliver continuously without overheating under standard operating conditions. It is a ... used when the motor is expected to operate for brief periods and then allowed to cool down....

A motor has to exert power starting from zero and rising uniformly to 150 HP in 8 mins after which it works at constant power of 100 HP for 5 mins. The motor remains on no load for next 5 mins. The cycle again starts and repeats indefinitely. Determine suitable size of motor.
Answer : --- ### What We Need to Do: We need to find the **equivalent power** of the motor. This is the steady power that the motor would need to operate continuously, while doing the same total work as in the cycle described. ... }. \] --- ### Final Answer: The motor should have a size of **61.1 HP**....
