I'm going through this article https://www.elttam.com.au/blog/intro-sdr-and-rf-analysis/ and I find it hard to understand the following part:
However, in our case we might want to transmit this signal later and need to represent each symbol with 1’s and 0’s, for instance the short pulse symbol may be represented by 0001. For this, we will measure the shortest pulse or gap that appears. Using the shortest pulse, we get a baud of 2960.
How did he calculate this 2960 rate? And why 0 should be represented as 0001 and 1 as 0111 - why 4 bits?
Thanks for your help
