I mean there are only 1's and no 0's

The main part ALU of cpu is responsible
for all arithmetic calculations.

If I want to design the ALU from scratch with
out the concept of binary, instead only with single
signal,
what are the difficulties one has to face.?

  First, getting somebody to make you a prototype. ;>)

for example see this
Eg: 5+5=10, instead of that
can I go with this technique
11111 + 111111 = 1111111111

  Sure, but five and six are eleven, not ten. ;>)

Thanks.

  How are you going to represent fractions?

  Large numbers will cause you trouble too. "Place" systems (binary,
octal, decimal, etc) allow large numbers to be represented by fewer
digits but you would apparently be forced to represent large numbers
directly. That is, to represent the value "one million" requires in
decimal seven digits, in binary 21 digits, but in your "placeless"
system one million digits.

  How are you going to store the numbers? Binary circuits use
registers with "places" corresponding to the values of the digits; the
first digit is "ones", the next "twos", the next "fours" and so on,
with ones or zeroes in each "place" to indicate whether there are any
of the digit in question. The values of two registers are compared
according to some rule and the result stored in another register.

  Your system, to do the same range of numerical calculations as a
binary system, will require 47619.047... times more memory since each
register will have to be that much larger in order to store the same
value as the binary register can.

  You're welcome, if you consider the foregoing "helpful".

Oh thanks.....for the clarifications

where I'm doing mistake.

you mean with the representation system of large numbers?

or some other .

please clarify here.

thanks
