Does anyone have a picture/image/link of what a biphasic square wave looks
like thanks.


If you mean biphase coding, it goes something like this:

(use a fixed pitch font like courier if it looks garbled)

1 0 0 1 1 0 data
| | | | | | | timebase

-. .-. .---. .-. .-
| | | | | | | | wave
| | | | | | | |
`---' `-' `-' `---'

AIUI it's similar to manchester coding,

notable features are that there's a state transition in the middle of every
bit, and between dissimilar bits, and that for bitrate b most of the energy
is between 1/2b and b Hz
