In reference to one interface control document, I found difficulty in understanding this concept. There is one parameter having LSB of 0.0625 and MSB of 2048 that should be transmitted from one piece of equipment to another. It's range is 0 to 2400.
This should be transmitted using only one word. That is 2 bytes.
Now the problem is: I understood this as that parameter is being measured by one measurement system with a resolution of 0.0625. Since it is decimal number how can we transmit this continuous range parameter using 2 bytes which are purely integers (unsigned range for 2 bytes is 0 to 65535)?
That parameter is speed, which is being measured by an INS-GPS avionics system and is being transmitted to the CPU using only 2 bytes.
How should I understand this?
How can we represent a continuous decimal parameter as a discrete integer parameter?
