A system has unit step response as shown below.


Impulse response of the system is

 
u(t) - u(t - 0.75) - 4(t - 0.75) + (t - 0)
u(t) - 4(t - 0.75) + (t - 1)
u(t) - u(t - 0.75)
u(t) + (t - 1)
Please type your answer before submitting.

We can not simply write the expression of r(t) as u(t). it is u(t)-u(t-2)

I am preparing for IBPS CWE PO exams. One of your advertisement shows that a special plan for IBPS CWE PO for 2 month is @ 500/-.. But I want to subscribe your annual subscription plan @975/- as I am preparing banking exam along with technical exams like GATE, IES , And PSU exams.. my question is whether the annual plan includes IBPS CWE PO plan or not ??? please call me back and clear my doubts asap....

Dear Satya, I don't know how is CWE PO 2 months @200/- subscriptions but still if you can purchase subscription plan @975/- it's better than 2 months subscription. It allows to you time management which give you increase your solving skills speed. Further better benefits of subscription plan @975/- that you can create chapter wise test which is best for you if you are beginners. At last check other website or give a test mail to get for logically solving question Orly of QA and Reasoning best website links and notes. mail id - [email protected]. I hope this will help to clear some of you doubts. Thanks Thanks
