Questions tagged [pulse]
A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. There are many examples of a pulse function including: Step/rectangular pulse, impulse/dirac pulse, triangular pulse, sawtooth pulse, sinc pulse, Gaussian pulse, etc.

Pulse signal conditioning with a LM311
I am trying to design a sensor to read the pulses on my electricity meter. The meter has 1 LED that gives 1000 pulses / KWh. Each pulse is 30ms in width. I am using a phototransistor and a LM311 to ...

Identify types of circuit(s) that would function as stated
I am trying to build a circuit that will have a trigger input, a clock input and an output that is (10) pulses at clock frequency for each trigger pulse.
Would it be multiple circuits (chips) or just ...

Measure time between trigger events
I want to measure the arrival time of three seperate digital pulses with respect to a global trigger.
The longest arrival time is expected to be <10ms and it would need to be able to determine the ...

Duty Cycle and Filtering in Switching Power Supplies
I have a few confusions to clear up. The first one is about the switching power supply.
Does the power supply simply work on the bases of the duty cycle? Like If I have a pulsating signal of 50% duty ...

Vary duty cycle in PULSE in LTSpice
In a simulation using LTSpice, I would like to sweep the on-time (duty cycle) of a pulsed voltage produced using the "PULSE" waveform.
I am able to run separate simulations using ".step&...

How to get rid of glitch?
I have designed simple P-channel MOSFET circuit. It works well, but when low source power is applied (1 V), a glitch occurs in the output signal.
I tried R, L and C component, but it didn't work.
What ...

Create TTL pulse with button press
Is there any way to get a 5V TTL signal (pulse of whatever duration, could even be a boxcar) from a button press with a very simple circuit or with some consumer device?
I need this to do some ...

How do I make this LFSR circuit generate random events every time the power is turned on?
I can't make this circuit work as expected and generate random events every time I turn on the power. I have checked NAND gates (IC3B, IC3C) and they generating clock signal with no problem. The only ...

What does the RMS value of a DC current waveform represent?
I understand (or at least think I understand) the math and calculation of RMS values and that it generally is used for representing equivalent power of non-DC circuits, like typical sinusoidal AC ...

How can I choose a capacitor for a very high energy pulse?
I need to specify capacitors for a very high power pulse application. Specifically, I need to deliver a pulse of about 7 kJ over 5 ms at a voltage of about 1 kV DC, so peak current is off the charts. ...
