Q:

A continuous signal can be represented as the product of an impulse function and the signal itself.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: The continuous signal can be represented as an integral of impulses. This representation buries it down to the form of convolution of two signal where one signal is the impulse function while the other is the continuous signal. Hence, the above statement is true.

Q:

The convolution of a discrete signal with itself is _________

A) Squaring the signal B) Doubling the signal
C) Adding two signals D) is not possible
 
Answer & Explanation Answer: A) Squaring the signal

Explanation: This is proved by the fact that since discrete signals can be thought of as a one variable polynomial with the coefficients, along with the order, representing the amplitude, at an instant equal to the order of the variable, of the signal- they are simply multiplied during convolution.

Q:

For a causal L.T.I. system, the impulse response is 0 for _________

A) t<0 B) t=0
C) t>0 D) Always
 
Answer & Explanation Answer: A) t<0

Explanation: Since the system is causal, the impulse response won’t exist for t<0. This is because the output of the system should not depend on future inputs. Thus only option t<0 is correct.

Q:

The signal get shifted by 1 units in time due to the following code: conv([ 1 2 3],[ 0 1 0 ]).

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: The 2nd row vector, in the input, acts like an impulse function delayed by 1 unit in time and exists only at t=1 unit in time. Thus, the above statement is true.

Q:

The output of p=conv([ones(1,50)],[ones(1,100)]) and p=conv([ones(1,100)],[ones(1,50)]) are same.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: The associative property of convolution suggests that convolving a and b is same as convolving b and a. Hence, the above statement is true.

Q:

What is the working of the conv2() command?

A) 2-d convolution B) 1-d convolution
C) 3-d convolution D) n-d convolution
 
Answer & Explanation Answer: A) 2-d convolution

Explanation: The conv2() command is defined in MATLAB to perform 2d convolution. Hence, only 2-d convolution is correct. This type of convolution is essential in image processing and video processing.

Q:

The unit step response of an L.T.I. system is the convolution of a step signal and it’s ________

A) Impulse response B) Ramp response
C) Parabolic response D) Time response
 
Answer & Explanation Answer: A) Impulse response

Explanation: The response of an L.T.I. system is given by the convolution of an input and the impulse response of the system. Hence, for the unit step response of an L.T.I. system- the input is a unit step function while the convolution will be done with the impulse response. Hence, Impulse response is correct.
