# Assignment No. 3 Semester: Spring 2015 Data Communication - CS601 Total Marks: 12 Due Date: 27/07/2015

Objective:

To have the understanding of Transmission Impairments

and Performance of Transmission Medium.

Please view the Assignment Submission Process document provided to you by the Virtual University for uploading assignments.

• Your assignment must be in Microsoft Word format.

(Any other format like scan images, PDF, Zip, rar, bmp etc will not be accepted)

• No assignment will be accepted through email.

• The submitted assignment does not open or file is corrupted.
• Your assignment is copied from internet, handouts or from any other student

(Strict disciplinary action will be taken in this case).

Question No.1:

Consider a noisy channel in which the value of the signal-to-noise ratio is 2500

and the channel capacity according to Shannon Capacity formula is 33840 bps.

Find its bandwidth? Provide your answer with full calculation and correct unit.

 Calculation Bandwidth with proper Unit

Question No. 2:

Suppose a signal travels through a transmission medium and due to some

reasons its power is reduced to quarter. You are required to measures the relative strength of this signal before and after power loss. Provide your answer with full calculation and correct unit.

 Calculation Relative signal strength before and after power loss with unit

Note: Give you solution with all relevant calculations in given tables.

HOw you solve from Line # 3 ????? Please tello

use calculatore/

 its power is reduced to quarter so 1 / 4 = 0.25
