Random signals are used to test dynamic response statistically for very small amplitudes and time-duration. Linear, stable and time-invariant. How it can be avoided? Aliasing refers to an effect due to which different signals become indistinguishable. It also refers to distortion in the reconstructed signal when it is reconstructed from the original continuous signal. To avoid aliasing we can simply filter out the high frequency components of the signal by using anti-aliasing filter like optical anti-aliasing filter. DSP processors are featured to support high performance and repeatitive and intensive tasks whereas microprocessors are not application specific and they are designed to process control-oriented tasks. Convolution is the technique of adding two signals in time domain. We can also do this quite easily by changing the domain of signals from time domain to frequency domain using Fast Fourier Transform FFT.

We can also do this quite easily by changing the domain of signals from time domain to frequency domain using Fast Fourier Transform FFT.

It is much more efficient then DFT and require less number of coding lines.

Due to FFT several kind of techniques are feasible. Interpolation is the process of increasing the sample rate in dsp whereas decimation is the opposite of this that is, it is the process of decreasing the sample rate in dsp.

Digital signal processing is a very important subject in b. DSP is a very important subject for Engineering and Diploma students. It is basically a numerical paper but it also consists of some very important theory portions that are required to be studied well as beginners. I think this article consists of almost all the basic questions that are and can be asked in ones Exam Viva during practicals. I would suggest interested students to go through the questions and prepare well.

For the ones who have interest in dsp can go through these answer and questions which can be helpful in gaining the knowledge.

The above article comprises of dsp interview questions. The ones who are interested can go through this.

About the Author: I have overall 6 years of experience in the Education Industry. Why Fft Is Needed?

Thus for large values of N direct evaluation of the DFT is difficult. By using FFT algorithm the number of complex computations can be reduced.

So we use FFT.

What Is Fft? It makes use of the symmetry and periodicity properties of twiddle factor to effectively reduce the DFT computation time.

It is based on the fundamental principle of decomposing the computation of DFT of a sequence of length N into successively smaller DFTs. What Is Dit Algorithm? The idea is to break the N point sequence into two sequences, the DFTs of which can be combined to give the DFt of the original N point sequence.

This algorithm is called DIT because the sequence x n is often splitted into smaller sub- sequences.

What Dif Algorithm? Answer : It is a popular form of the FFT algorithm.
