No, it's not Propagation delay
Its the time difference between how fast the Op-amp comparator switches from input to output
They could be opamps or comparators or something else.Are these Op-amp comparators? or are they something else
You need to look at the schematic and figure out how it works.How can you tell when an Op-amp circuit or a comparator is tripped by current and not voltage?
Or both. I certainly don't. Maybe this is related to his other thread about RC delays.Then either I have no idea what you are talking about, or YOU have no idea what you are talking about.
A series current sense resistor can be used to develop a voltage drop that can feed a comparator IC.
comparator IC to see a description and graphs of its "response time"
You typically measure the "response time" of a comparator between the input change and the output change with an oscilloscope.
A comparator IS NOT an opamp but you are talking about both of them.
The design of a 741 opamp is 46 years old so its switching response time is very slow. A resistor in series with its input and a capacitor parallel to the resistor boosts the speed of the signal to its input. Is that the RC network you talked about?How do you measure the time of just the Input change?
The Input can have an RC network to the input pin of the IC , so how do you measure the Input change time?
It is a slow opamp used as a slow comparator.Since they aren't comparator IC chips , what is it called when you use an Op amp that has a voltage threshold or is compared with a fixed DC reference Input pin?
A resistor in series with its input and a capacitor parallel to the resistor boosts the speed of the signal to its input. Is that the RC network you talked about?
It is a slow opamp used as a slow comparator.
A series resistor then a capacitor to ground (or to the supply voltage) is a simple lowpass filter that causes a delay. (It is a lagging network)
A series resistor with a capacitor in parallel is a simple highpass filter. (It is a leading network)
