Digital Signal Processing Internship Test

Intern has to take Digital Signal Processing internship test in which they will be asked 50 multiple-choice questions. They have to score grade A or A* on this test to be eligible for the internship. Here’s a sample set of questions on the Digital Signal Processing topic.

1. An FIR system is also called as “recursive system”.
(A) True
(B) False
View Answer

Answer: B
Explanation: For a system to be recursive, the output of the system must be dependent only on the past values of the output. For an FIR system the output of the system must be depending only on the present and past values of the input. So, FIR system is not an recursive system.

2. The solution obtained by assuming the input x(n) of the system is zero is ____________
(A) General solution
(B) Particular solution
(C) Complete solution
(D) Homogenous solution
View Answer

Answer: D
Explanation: By making the input x(n)=0 we will get a homogeneous difference equation and the solution of that difference equation is known as Homogenous or Complementary solution.

3. If x(n) is a discrete-time signal, then the value of x(n) at non integer value of ‘n’ is?
(A) Zero
(B) Positive
(C) Negative
(D) Not defined
View Answer

Answer: D
Explanation: For a discrete time signal, the value of x(n) exists only at integral values of n. So, for a non- integer value of ‘n’ the value of x(n) does not exist.

4. If a system do not have a bounded output for bounded input, then the system is said to be __________
(A) Causal
(B) Non-causal
(C) Stable
(D) Non-stable
View Answer

Answer: D
Explanation: An arbitrary relaxed system is said to be BIBO stable if it has a bounded output for every value in the bounded input. So, the system given in the question is a Non-stable system.

5. The system described by the input-output equation y(n)=nx(n)+bx3(n) is a __________
(A) Static system
(B) Dynamic system
(C) Identical system
(D) None of the mentioned
View Answer

Answer: A
Explanation: Since the output of the system y(n) depends only on the present value of the input x(n) but not on the past or the future values of the input, the system is called as static or memory-less system.
