50HZ. Is it important if we do work on this IC?What are the frequencies of the two AC signals?
Just checking.50HZ. Is it important if we do work on this IC?
So how would you do that, other than with a calculator?I think the way in which I had described the issue is not perfect. Sorry. Actually, I dont need to divide actual sine wave but I need to divide two AC values read by multimeter.
Exactly!! I was looking for a circuit to get output reading directly and bypass calculator uses.So how would you do that, other than with a calculator?
In this case, answer will be in DC itself. But required answer (division) should be in AC.In that case, take the two AC signals, rectify and smooth to DC and then do the division.
You still have not answered the fundamental question of what you expect to happen when the divisor approaches zero from either direction. The answer is that you cannot make meaningful sense of the result. This fact makes your entire process suspect.I
In this case, answer will be in DC itself. But required answer (division) should be in AC.
That statement makes little sense.In this case, answer will be in DC itself. But required answer (division) should be in AC.
The IC will divide the two DC representations of the AC signal amplitudes.I may misinterpret this division part of this IC.
You just want a digital readout like what is shown on a DMM. Is that correct?In this case, answer will be in DC itself. But required answer (division) should be in AC.
Let me try to rectify both signal then give input to AD532. Answer in DC will be OK.That statement makes little sense.
What do you mean the answer should be AC?
The multimeter displays a digital number that is a steady DC representation of the ACrms magnitude of the signal.
The answer from the divider will be a digital voltage representing the ratio of the two signal amplitudes, which can be converted to a digital number by an A/D converter if you like.
The IC will divide the two DC representations of the AC signal amplitudes.
If the divisor gets near zero than the output of the divider will saturate at its maximum value since the answer is becoming a very large value (approaching infinity as the divisor goes to zero.)
So what will be the minimum divisor signal level?
And what is that answer used for?
I just want to divide two multimeter read outs (while knob on AC option on multimeter) without using any calculator.You just want a digital readout like what is shown on a DMM. Is that correct?
What is your definition of AC?
The readout can be scaled by any factor you choose.
Minimum value will vary from 0.1V to almost 3V (while knob is on AC option on multimeter)Tha
Let me try to rectify both signal then give input to AD532. Answer in DC will be OK.
That answer is just to note down.
