Signals and Systems Interview Questions and Answers

What we have to do, if the spectrum of a discrete signal is to be expanded? Answer: If the spectrum of a signal is having even symmetry around zero frequency then the signal is said to have zero phase. How you can represent recursive and non-recursive discrete time system with the help of constant coefficient difference equation? Answer: When a signal is sampled and FFT is performed directly then the first side lobe is only 14 dB less than the main lobe i. Windowing of sampled signal is done to improve the ratio between main lobe and the first side lobe. What should be the condition for the time domain system to be stable and causal both? Answer: The system is stable and causal both if all the poles lie in left half side of s-plane and ROC of Laplace transform is on right hand side of all the poles i.

What is meant by step response of the DT system? The output of the system y n is obtained for the unit step input u n then it is said to be step response of the system. Define Transfer function of the DT system. The Transfer function of DT system is defined as the ratio of Z transform of the system output to the input. Define impulse response of a DT system.

Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море. Это был ТРАНСТЕКСТ, компьютер, равного которому не было в мире, - шифровальная машина, засекреченная агентством. Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью. Ее секрет был спрятан в керамических шахтах, уходивших на шесть этажей вниз; ее похожий на ракету корпус окружал лабиринт подвесных лесов и кабелей, из-под которых слышалось шипение фреоновой системы охлаждения.

Его нижняя губа на мгновение оттопырилась, но заговорил он не. Слова, сорвавшиеся с его языка, были определенно произнесены на английском, но настолько искажены сильным немецким акцентом, что их смысл не сразу дошел до Беккера.
