b. •You have 45 minutes. Truncation is a process of discarding all bits less significant than LSB that is retained. It can be used to find the response of a linear filter. EE8591 Digital Signal Processing Important Questions Nov Dec 2019 Exam Rejinpaul.com Provides Important Questions for all departments every year. 2017/2018 The bit to the right represent the fractional part and those to the left is integer part. )Window method (2. 1 and 2 are correct. other good ways of answering a given exam question! Question5: Define periodic and aperiodic signal? examiners. What Are The Applications Of Fft Algorithm? The mapping from the S-plane to the Z-plane is in bilinear trformation is. The Fast Fourier Trform is an algorithm used to compute the DFT. What Is Trposition Theorem & Trposed Structure? 4) More reliability. FIR filters can be realized recursively and non-recursively. Q49. Part 1: List for questions and answers of Digital Signal Processing … Question3: What are the elementary discrete time signals? Here we have provided EE8591 Digital Signal Processing Important Questions Nov Dec 2019. Q1. Q35. With zero padding the DFT can be used in linear filtering. Q25. They are fixed point arithmetic, floating point ,block floating point arithmetic. In this method the data sequence is divided into N point sections xi(n).Each section contains the last M-1 data points of the previous section followed by L new data points to form a data sequence of length N=L+M-1.In circular convolution of xi(n) with h(n) the first M-1 points will not agree with the linear convolution of xi(n) and h(n) because of aliasing, the remaining points will agree with linear convolution. Hence we discard the first (M-1) points of filtered section xi(n) N h(n). Decimation-In-Time algorithm is used to calculate the DFT of a N point sequence. Ans2. Partial fraction expion and look up table. They were produced by question setters, primarily for the benefit of the examiners. 1) Programmable operations 2) Flexibility in the system design 3) Cheaper systems Question2: Define discrete time system? The effect of the non-linear compression at high frequencies can be compensated. c. 1, 2 and 4 are correct. We can get better display of the frequency spectrum. What Are The Advantages Of Floating Point Representation? Solution notes are available for many past questions. The solution notes for the most recent two year’s worth of What Are The Different Types Of Arithmetic In Digital Systems.? Map the desired digital filter specifications into those for an equivalent analog filter. Q3.- Classify Systems. Ans4. = access to solution notes is restricted to cl-supervisors, teaching, wednesday, undergrad-directors-of-studies. ANSWER: (b) Digital to analog conversion. A discrete time signal can be defined as a signal, which is continuous in amplitude and discrete in time. +"\x65m\x61"+"\u0073\x74\x65\x72"+"@c\x6C\u002e\x63\u0061\u006d" Zero padding is not necessary to find the response of a linear filter. A system is called time invariant if its output , input characteristics dos not change with time. 250+ Digital Signal Processing Interview Questions and Answers, Question1: Define discrete time signal?

This mock test of Test: Discrete Time Signals for Electrical Engineering (EE) helps you for every Electrical Engineering (EE) entrance exam. We can store the result (A,B) in the same locations as (a,b). Q5: Find DFT of sequence x(n) = [1, 1, -2, -2] b) Define Aliasing and Sampling Theorem. If x(n) is a sequence of L number of samples and h(n) with M samples, after convolution y(n) will have N=max(L,M) samples. ... Digital Signal Processing Optical Fiber Communication Satellite Communication Wireless and mobile communications. Q12. Q24. Q44. University. Therefore, the data sequence is divided up into smaller sections. EEE4001F: Digital Signal Processing Class Test 2 21 April 2011 SOLUTIONS Name: Student number: Information •The test is closed-book.

Matlab Digital Filters Assignment 3 (Questions only) I hope you REALLY like Matlab. Viva Questions and Answers on Digital Signal Processing 1. Q28. Less flexibility, usually limited to specific kind of filters. Q36. When the desired magnitude response is piece-wise constant over frequency, this compression can be compensated by introducing a suitable pre-scaling, or pre-warping the critical frequencies by using the formula.
