Abstract

The transmission of data represented as binary numbers ranging from zero to 2/m/, where m is a constant defined by the information to be sent, normally requires m channels transmitted in parallel p times or for one channel m times p transmitted serially, where p is equal to the amount of numbers in the set.

Segmented Transmission of Digital Data

The transmission of data represented as binary numbers ranging from zero to 2/m/, where m is a constant defined by the information to be sent, normally requires m channels transmitted in parallel p times or for one channel m times p transmitted serially, where p is equal to the amount of numbers in the set.

If the data to be transmitted is in increasing order of magnitude, segmented data transmission will take advantage of the increasing magnitude of the numbers and divide transmission into two operations differentiated at a receiver 3 by a control channel 21. The n high-order digits 31 change relatively few times when compared to the m-n low-order digits 32. Therefore, the n high-order digits are sent to the receiver with a "1" in the control channel 21. These transmissions are in addition to the p times the other m-n digits are sent with the control channel equal to "0". At the transmitter 1, a control bit 11 is generated according to the nature of the information to be transmitted. If the high-order n digits 12 are to be transmitted, the control bit 11 is a "1". If the low-order m-n digits 13 are to be transmitted, the control bit 11 is a "0".

Thus, the maximum number of channels required to transmit data is m-n channels 22. The maximum number of digits sent is (m-n+1) (p+2/n/) as opposed to p x m digits sent using normal transmission where: m is the number of digits in each number, n is the segmented length, p is the amo...
