ak aur assignment copy paste he karni hai girls nay  tens kiss baat ki phir       ji nai malik shayan bhai girls just copy pASTE nai krti

SB NY HE COPY PASTE KRNI HOTI HY MOSTLY IS LYE TU KOI BHE TENS NAE HOTA                     Ye to bilkul sahi kha aap ne

ans of 3rd question...

In ASK, Baud Rate =Bit Rate

Baud Rate=3

Also ASK requires a minimum bandwidth equal to it’s baud Rate

Minimum BW=3Hz

Regard Malik shayan......

ye ans thk ha????

yes

Our main purpose here discussion not just Solution

We are here with you hands in hands to facilitate your learning and do not appreciate the idea of copying or replicating solutions.

Question. 1                                                                                                              (5 Marks)

Consider a periodic signal which is decomposed into seven sine waves with frequencies 300, 200, 1000, 600, 800, 700 and 400 Hz, what is the Bandwidth of this signal? Give your answer with complete calculations and proper unit in a given table.

 Calculation Bandwidth Unit Bandwidth= higher frequency-lower frequency=1000Hz-200Hz=800Hz 800Hz 7

Bandwidth of Signal =800Hz

Tariq bhai it is not fair app ne meri post delete kar k . yahan post kar diya ...
