Digital Electronics - Digital Signal Processing

Random signals are used to test dynamic response statistically for very small amplitudes and time-duration. 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.

Define discrete time and digital signal. Discrete time signal is continuous in amplitude and discrete in time, where Digital signal is discrete in time and amplitude. Explain briefly, the various methods of representing discrete time signal Graphical, Tabular, Sequence, Functional representation. Define sampling and aliasing. Converting a continuous time signal into discrete time signal is called as Sampling, Aliasing is an effect that causes different signals to become indistinguishable. What is Nyquist rate?

I was interviewed in Aug, Interview Questions Q1. I was asked to implement the block diagram for the given transfer function. Add answer Q2. Is the system with the given transfer function stable? Add answer Q3.

Answer: A function of one or more independent variables which contain some information is called signal. A system is a set of elements or functional blocks that are connected together and produces an output in response to an input signal. Answer : A signal is what which contains information while wave does not contain any information. Answer: A deterministic signal can be completely represented by mathematical equation at any time whereas a signal which cannot be represented by any mathematical equation is called random signal. What will be the signal in the frequency domain when a signal is discrete and periodic in time domain?

His hand slipped into the neckline of her chemise and cupped her bare breast. He represented the conservative party of the court. You take her out for a few hours and she comes home with a hairless dawg! Openstack Interview Questions And Answers for

Reconfiguration Reconfiguration of analog circuits require redesigning the hardware followed by testing and verification where as DSP chips can be easily reconfigured by changing the software. Accuracy DSP has higher accuracy. Storage Digital signals can be easily stored on magnetic disks hence easily transported and stored for offline processing Precision It is difficult to perform precise math operations on analog signals but DSP algorithms are easier to implement and can attain precision as well. Cost DSP is cheaper than its analog counterpart. What are the differences between a microprocessor and a DSP processor?

Digital Signal Processing Interview Questions & Answers

Стратмор продолжал: - Несколько раз Танкадо публично называл имя своего партнера. North Dakota. Северная Дакота.

Результатом будет полнейший хаос. - А Фонд электронных границ будет праздновать победу, - побледнела Сьюзан. - Фонд понятия не имеет о том, чем мы тут занимаемся, - презрительно бросил Стратмор.  - Если бы они знали, сколько террористических нападений мы предотвратили благодаря тому, что можем взламывать шифры, они запели бы по-другому. Сьюзан была согласна с этим, но в то же время прекрасно понимала: Фонд электронных границ никогда не узнает, насколько важен и нужен ТРАНСТЕКСТ. Эта машина помогла предотвратить десятки преступлений, но связанная с ней информация строго засекречена и никогда не будет раскрыта.

Стратмор, в свою очередь, тоже сгорал от нетерпения, но подругой причине. Если Дэвид и дальше задержится, придется послать ему на помощь кого-то из полевых агентов АНБ, а это было связано с риском, которого коммандер всеми силами хотел избежать. - Коммандер, - сказал Чатрукьян, - я уверен, что нам надо проверить… - Подождите минутку, - сказал Стратмор в трубку, извинившись перед собеседником. Он прикрыл микрофон телефона рукой и гневно посмотрел на своего молодого сотрудника.  - Мистер Чатрукьян, - буквально прорычал он, - дискуссия закончена.

Digital Signal Processing Interview Questions & Answers

Беккер шел, низко опустив голову. Халохот прокручивал в голове дальнейшие события. Все было очень просто: подойдя к жертве вплотную, нужно низко держать револьвер, чтобы никто не заметил, сделать два выстрела в спину, Беккер начнет падать, Халохот подхватит его и оттащит к скамье, как друга, которому вдруг стало плохо.

 Ах ты, мерзавка! - крикнул он, скорчившись от боли. Сьюзан бросилась к двери, моля Бога, чтобы Стратмор в этот миг включил резервное энергоснабжение и дверь открылась. Увы, ее руки уперлись в холодное стекло.
