Please Discuss here about this assignment.Thanks

Hello Sir, pleased to be part of ur group

 

See the attached file for Solution of CS101 Assignment#02 Spring 2011

Good Day Mr Tariq Malik:

u always used to help the students in making assignments,

but respected sir, there is a problem that i have noticed, u always done a mistake in ur assignments.

like, in recent one, u have prepared a truth table, there is a mistake in (w+x) {the forth last result}, it should be "1" not "0". as in OR gate, if any one of the inputs is True (1) the result would be True (1).

i hope u will not mind, and if u felt that i m wrong, then u would correct me by giving explaination.

 

keep helping out us,

Best Regards:

mc110200242 - MBA - 1st Semester

The answer will be 2^n where n=number of inputs



so 2^9 = 1024 combinations.



i hope this is the answer of question no.1 (a)
dont fool the students by your wrong answers 2^9 is 512
sorry i made a mistake............ every one plz forgive me!!!!!!!!!!!

@ M.Amir.M.. are u sure that limitations of word processor and Spreadsheet are correct.

Question No.1 (Marks = 10)

a) How many combinations of bits are exist when we make a truth table of 9 inputs?

            2n are the total combinations of bits in Truth table, where n is number of variables, so

29=512

            512 bits will there

 

 

b) Prepare a truth table for the following I = (w + x) Å (y . z) where w, x, y and z are four binary inputs in the truth table.

Note :(Å  symbol represent XOR gate)

Solution:

Remember in XOR, output will high only if only all inputs are mismatch to each others.
