thanx to all of u suba mra paper ha plz sb dua kr dena

Sheikh Prince Welcome 

kal mera paper h plz dua krna

pareezy

Q no 6

Calculate bit rate & bund rate for an analog signal transmitting 500 signals per sec, where each signal element carries 5 bit.

–Baud Rate= Number of Signal Elements
–Baud Rate =500 bauds/second
–Bit Rate=Baud Rate * Number of bits per signal element
–Bit Rate= 500 * 5 = 2500 bps

Q no 5

Consider a carrier signal whose phase & frequency remain constant varying amplitude, which kind of modulation will take place?

in ASK Both frequency and phase remain constant, while the amplitude changes

Q no 3

Despite of having digital signals why we need to have digital to analog conversion of  signal? Explain with example.  

We might want to send a digital signal coming out of computer through a medium designed for analog signals
For example, To send data from one place to the other using a Telephone line. This is called “Digital-to-Analog Conversion” or “Modulating a digital Signal”

Q no 2

Consider a dialup modem for modulating digital data to analog signals suggest the most efficient technique used for modulation?

QAM is the most efficient of these options and is the mechanism used in all modern modems

Q no 1

What is zero frequency & hoe it effect on signal?

zero frequency means a signal has no change in one second. When a signal contains zero frequency, it cannot travel through a Tx. Medium that cannot handle it.

Why RZ requires more bandwidth than NRZ ?

beacuse it requires two signal changes to encode one bit and therefore occupies more BANDWIDTH

Q no 5

Consider a carrier signal whose phase & frequency remain constant varying amplitude, which kind of modulation will take place?

in AM Both frequency and phase remain constant, while the amplitude changes

Cs601 Current midterm may 2013

short q mein se 
1:polar aur bipolar ki diff types ka naam likhna tha
2: given digatal signal ko NRZI k lihaz se show karna tha(kisi ko pta hai k es ko kis chez pay bana k show kia jata hai ta k nxt time to mai kuch kr k he aaon,i mean paint mein ,wordpad ya phr graph??)
3:given bw k lihaz se ASK k liye boud rate aur bit rate maloom karna tha
kuch mcq past pprz mein se thay 
aur yehi aj ka mera ppr tha jo intahi kharab hua plz duaon mein yad rakhye ga :)

yes, I have attended my paper at 30.05.2013 on thur..
there are previous ques of mcqs mostly and in subjective i have this ques..5 marks
Q no 6
Calculate bit rate & bund rate for an analog signal transmitting 500 signals per sec, where each signal element carries 5 bit.
and mostly ques was about AM, FM & Bandwith in subjective...SO, Remember all the formulas...just some formulas not more...
