I need to find out whether the Collision detection circuitry in the IEEE 802.3 network cards is either analogue or digital. An explanation of whatever the answer is would help.

Digital.

(1) IEEE 802.3 is the standard for ethernet. Ethernet signals are all digital.
(2) The only time a computer will see an analog signal is when the signal is transmitted by using a modem (modulator / demodulator). Please understand that what we commonly refer to as cable and DSL modems are not really modems they are network adapters that are made specifically for that particular application.
(3) Computers do not understand analog information. Everything is 1's and 0's to a computer.

Digital. Why? Because the wireless data is digital... P2E
