ECE :: Signals and Systems
-
what will be sampling rate to aviod aliasing for the signal m(t) = 10 cos 100 pt?
-
Choose the function f(t), - ∞ < t < + ∞, for which a Fourier series cannot be defined
-
Assertion (A): The number ∈ such that the probability that an error is between -∈ and + ∈ is 1 is called probable error of single obserevation.
Reason (R): The standard deviation is the arms value of the deviation from the arithmetic mean.
-
Which of the following is the correct Laplace transform of the signal shown in the given figure
-
If x(t) and its first derivative are Laplace transformable and Laplace of transform x(t) is X(s), then
x(t) is -
If a function has only cosine terms, it must satisfy the equation
-
If v(t) is a time varying voltage,
is -
The data of speed of train V and resistance to motion R is
The law R = a + bV2 is of the form

originating at t = 0 and another ramp with slpoe 
and originating at t = T. Thus
