dear sir,
i have one more question.
when we talk about sending data in bits and talk about symbols- i want to just know the big picture here.
suppose i have to transmit letter 'A' and suppose the binary is 11000110. so every bit is transmitted as a symbol ( i.e. a combination of bits which we decide as above ) or is a 1 transmitted as 1 only followed by another 1 followed by three zeroes etc.
to say it other way is there a mapping of 0 and 1 with symbols as designed by engineers at the physical layer or have i mixed it up.
