Question 1
Which of the following signal is obtained on integrating ramp signal?
Question 2
A signal x (t) is defined in the range – 5 ≤ t ≤ 5 and has energy of 16 units. If a new signal y (t) is formed by transforming x (t) is given as then the energy of the new signal y (t) will be _________ units.
Question 3
L{e–2t [u(t) – u(t – 1)]} = ?
Question 4
Consider the signal x(t) and h(t) given below as
x(t) = te—2t u(t)
h(t) = te—4t u(t)
a signal defined as y(t) = x(t) * h(t)
Where * denotes the convolution.
y(t) is represented as.
Then find the value of A + B + C + D
