is there a way to detect each pulse of a signal

[AnkitG]

Hi All,

I need to detect every pulse of my input signal pulse, is there a way to do that, I tried using basic level triggering but the trigger doesnot switch true and false between pulses.

I need to detect the input pulse for some ms  and then generate an output pulse at the falling edge of the input pulse.

can someone tell me way to do that, i do have a daq board usb 6361, but couldnt find a proper way to do something like this.

my input signal frequency varies between 100-450 hz with amp -0.1v and pulse width of 5 microsecond

What kind of hardware are you using?

My main concern here is the 0.1V amplitude of the pulse.  What is the normal voltage when the pulse is not being sent?

I am using USB DAQ 6361 with BNC's. The input signal pulse voltage is -0.1v but I need the output pulse to be + 2 V.

I didnt understand that. Normally when there is an input pulse the voltage is around -0.1v and when not then o v. I need to generate the ouytput pulse at the falling edge of the input pulse of 2v

I think we can do this with some extra circuitry.  First of all, we need to gain up that input puse to be a +5V.  You will need an inverting amplifier with a gain of 50.  Now you have a TTL level signal that you can feed into a PFI line to use as a trigger.  You can use an analog output to output a waveform (your 2V pulse) when that trigger line goes high.
