It's an ambiguous question, because technically all signals are analog. The short answer is no. By asserting they are logic gates, you are supposing digital logic criteria and analysis: high impedance input, nominal output impedance, the transistor's operating regions are either saturation or cutoff, and the I/O signals are analyzed in discrete steady-states. Digital signals are applied to logic gates as the distinction of "digital" establishes the above signal criteria and circuit operation.
nor as well as nand gate are universal gates they both can be used as a complete set of logic gates

All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).
The combinational logic circuits are a type of logic circuits containing only logic gates (AND, OR, XOR, NOT, NAND, NOR) and its output only depends on the current input (do not have memory).
limitations of logic gates
No, logic gates work on low voltage signals typically at 3.3V or 5V. 240V is a high voltage that is typically used for powering devices in electrical systems. Logic gates are electronic components that process digital signals and perform logical operations based on the input signals.
AND - true if both/all inputs are true OR - true if any input is true XOR - true if one input is true and one input is false NOT - true if input is false
types of optical logic gates
The input to the earphones is a a analog signal i.e., electrically generated analog signal.
logic gates comes under semiconductor
All digital electronic circuits are composed of logic gates. Without logic gates there would be no digital electronics.
And, OR and Not gates.
