That's strictly an analog circuit, nothing digital about it.
Yes.
A diode can be used in an analog circuit (and is used in many of them) without making it digital.
Do you really think that any circuit with a diode is digital?

I am making note of the IC1B operation when V2>V1.
What else do you call a Analogue signal if it gets rectified into a ????? signal.
Or we could say what happens when a AC gets rectified ?????

 

hi menyman,
Hope you can follow this LTS sim OK.
R12 is the resistor in question.
The Switch connects R12 in the feedback loop for a given period.
The Vb[V2] voltage is applied as a +1v pulse, during the pulse R12 is switched In and Out.

From the sim results I would conclude that R12 is there to set Vout [Voo] to 0V when there are no input voltages on V1 or V2.

It's called a rectified analog signal.
The result is generally some form of unidirectional or DC voltage.

Digital signals carry the information in discrete steps (typically binary or 1 and 0).
Signals with indefinite or arbitrary values are analog.

Look of the definitions of analog and digital.

 

Hi Guys,

Again thanks for helping analyzing the circuit.
After a second look I believe it should be a lot easier to look at if we'll just go with the op amps rules, we can see that the negative feedback takes care of everything:

Hi crutschow,

So a signal that doesn't go below 0V-+ & only goes into positive is a rectified analogue signal lol.
I suppose a AC is negitive digital signal in that case ????
& a DC is a constant linear analogue ????

All I know is that the internals of a opamp are through gated transistors & a transistor that is gate controlled by a analogue signal creates a DC output or even a PWM.

May I please ask what your qualification is ?

Only if you tell me yours.

Yes.

No.

If the DC varies and the value represents a signal, then it's analog.

The DC output is analog.
PWM is a digital representation of an analog value.

So what's your definition of analog and digital?

He is an old newbie. He is starting to learn electronics. Bear with him.

I find fascinating people like you coming into the forum daring to post so surprising statements. Go ahead. Give us more of your wisdom.
