Thanks for you info.
Yes, I have seen this, one clock signal is 180 degrees out of phase with the other one.
Any reason why they want the clock signal to be 180 degrees or have a 2 phase clock signal?
So inverting the logic state, turns a Positive logic truth table into a Negative truth table?
So A sine waveform has no slew rate?
They use Non-Inverting Schmitt triggers to convert a sine wave into a square waveform.
What's the difference between using an op amp to convert a sinewave into a square waveform or using a non-inverting schmitt trigger?
I have seen circuit that use either op amp or non inverting schmitt trigger to convert a sinewave into a square waveform but what is the difference between using an op amp or using a non-inverting schmitt trigger?
Yes this is how I looked at negative logic truth tablesand the OR truth table:
a b c
0 0 0
0 1 1
1 0 1
1 1 1
If we invert all the zeros and ones in the OR table we get:
a b c
1 1 1
1 0 0
0 1 0
0 0 0
What kind of timing signals have you seen what are bad or was causing problems?Of course you check the timing of the circuit too, to make sure the signals occur at the expected times
What you mean by test patterns? for CMOS and TTL?This means test patterns have to be created very carefully depending on the logic family.
Do you have to set up the logic analyzer for 10 percent to 90 percent amplitude?Often the 10 percent and 90 percent wave amplitudes are used as the thresholds for measurement.
Which menu do I go to on the o-scope to set it up for 10% to 90% points? I'm not sure how i set up my o-scope for this measurementThat's for when you use the scope. You look at the point where it crosses the 10 or 90 percent point (of the max amplitude) and use that as the switch point.
