Can somebody post a 1-bit ADC circuits diagram with its components ?

Is this a homework question?

Any digital input is a 1-bit ADC.

NO.
I want a circuit diagram with its components.

If you want another answer, here is a circuit diagram:

We should invite Yakima the tutor to offer a solution.

How can I make circuit from above diagrams since you are not giving component models numbers ?

What's the purpose of this 1 bit ADC, two bits have four status maybe more useful.

What is the transfer function of a 1-bit ADC?

I want to interface a LDR to this 1-bit ADC to get 0V and 5V outputs.

I have no idea about that.
If you could just give me a circuit that only gives 0V and 5V as outputs when connect a LDR to its' input.

What is the resistance of the LDR?

Dark resistance = 1M
light resistance = 500R

"TORCH_LDR" in Proteus 8 software.

So you need a op amp schmitt trigger to set as voltage comparator.

OK, If could please give me the circuit diagram of it with real components.

You will need the circuit like this.

yes, with component vales and model names.
