Todays paper is so much easy but confused...

20 MCQs 40% from Mooaz File and others are new but confused....

short questions of 2 and 3 marks... are from signal conversion... synchronous....

5 marks question from DETs and DECs and aik conceptual tha....

Overall paper from lecture 14 to 22 especially for 5, 5 marks subjective...

Kindly pray for me..... All Exams clear ho jae..... 

Nadia gull thanks for sharing.keep it up

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

Q no 3

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

Q no 4

Sketch the Manchester’s encoding for the stream “01100”.

Q no 5

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

Q no 6

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

paper was conceptual.

define DTE, DCE

Bit Interval

find sample rate

find baud rate

and MCQs some from old and some new, 50%, 50%
