The digital signal bandwidth is high Analog hardware never offers flexible implementation Digital hardware offers flexibility in implementation It is suited for audio and video transmission It is suited for Computing and digital electronics The Analog signal doesn't offer any fixed range Digital signal has a finite number, i e, 0 and 1. Analog and digital communication As a technology, analog is the process of taking an audio or video signal the human voice and translating it into electronic pulses Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s Digital signals are immune to noise, quality of transmission and reception is good, components used in digital.

Analog Communication Interview Questions & Answers

What are the disadvantages of Analog communication? What are the Advantages of Digital Communication? Reliable, Noise effect is very less, power consumption is very less, various Digital ICs are available so circuits not complex , cheap, Error detection and correction is also possible. What are different types of digital modulation?

How to convert an analog signal into digital signal? Define the functionality of Sampler, Quantizer? Sampler: converts a continuous time signal into discrete time signal. Quantizer: converts continuous in amplitude signal into discrete in amplitude signal. What are some Coding techniques? Pulse code modulation, Differential pulse code modulation, Delta modulation, Adaptive delta modulation. What is Sampling? Converting a continuous time signal into discrete in time signal is called as Sampling similar to cutting a bread into slices 8.

Define Sampling theorem? To reconstruct the Continuous time signal from discrete time signal ,the sampling frequency should be more than equal to twice of Continuous time signal frequency max. What is Nyquist Rate? If the sampling frequency is twice of Continuous time signal frequency max , then that is called as Nyquist rate.

How many types of samplings are their? Explain briefly? Impulse Sampling, Natural sampling, Flat top sampling. What is aliasing effect? How to overcome it? Due to imperfect sampling the signals will be interfered in frequency domain i. What are the Analog pulse modulation methods? Pulse amplitude modulation, pulse width modulation and pulse position modulation.. Define Pulse amplitude modulation? Define Pulse width modulation? Define Pulse position modulation?

It represent the digital data as variations in amplitudes in carrier wave. What is Phase shift keying PSK? It represent the digital data as variations in phase shift in carrier wave. What is Frequency shift keying FSK? It represent the digital data as variation in frequency in carrier wave, i. What is the difference between Bit Rate and Baud Rate?

Bit rate represents Bits per sec, Baud rate represents no. What is bandwidth of BPSK signal? When input data is 1 then output is carrier, if input is 0 out put is zero.

Analog Communication Interview Questions and Answers

Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices. The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing. When a switch receives a signal, it creates a frame out of the bits that were from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port.

What is Electronic? The study and use of electrical devices that operate by controlling the flow of electrons or other electrically charged particles. What is communication? Communication means transferring a signal from the transmitter which passes through a medium then the output is obtained at the receiver.

What is sampling? What is Sampling Theorem? Ans Sampling is defined as the process in which an analog signals are converted into digital signals. It means that a continuous time signal is converted into a discrete time signal. You might not require more epoch to spend to go to the ebook start as without difficulty as search for them.

Джабба повернулся к монитору и вскинул руки.  - Почему среди нас нет ни одного ядерного физика. Сьюзан, глядя на мультимедийный клип, понимала, что все кончено. Она следила за смертью Танкадо - в который уже .

Да будь они прокляты, эти криптографы. Ничего не понимают в системах безопасности. Присяга, которую Чатрукьян принимал, поступая на службу в АНБ, стала непроизвольно прокручиваться в его голове. Он поклялся применять все свои знания, весь опыт, всю интуицию для защиты компьютеров агентства, стоивших не один миллион долларов.

Это был высокий мужчина крепкого сложения с густыми светлыми волосами и глубокой ямкой на подбородке. Он отличался громким голосом и безвкусно-крикливой манерой одеваться. Коллеги-криптографы прозвали его Галит - таково научное название каменной соли.

 Рыжие волосы, - повторил Беккер, понимая, как глупо выглядит. - Простите, у нас нет ни одной рыжеволосой, но если вы… - Ее зовут Капля Росы, - сказал Беккер, отлично сознавая, что это звучит совсем уж абсурдно. Это странное имя, по-видимому, не вызвало у женщины каких-либо ассоциаций. Она извинилась, предположила, что Беккер перепутал агентство, и, наконец, положила трубку. Первая попытка закончилась неудачей.

Сьюзан, подшучивая над ним, часто говорила, что напоить его не составляет никакого труда. Наполнив тяжелый хрустальный стакан водой из фонтанчика, Беккер сделал несколько жадных глотков, потянулся и расправил плечи, стараясь сбросить алкогольное оцепенение, после чего поставил стакан на столик и направился к выходу. Когда он проходил мимо лифта, дверцы открылись. В кабине стоял какой-то мужчина. Беккер успел заметить лишь очки в железной оправе.
