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.

Do commercial products exist for lab-scale thyristor triggering?
Hello fellow stack exchange members!
We're excited about our novel high-voltage voltage-source-converter design that utilizes SCRs/thyristors and commutation circuits. We're now looking to build a ...

How to generate a single pulse for certain milliseconds or second without microcontroller?
I'm using an IR sensor as an input and I want that when IR sensor (A) goes high, then a single 300-ms pulse is generated at (B), such that even if (A) stays high, it doesn't generate any other signal ...

How can I boost the output current of this pulse generator (LF353, supplied with ±15 V) to above 25 mA?
I have a pulse generator design. Everything works fine, but it is required that the output current is above 25 mA. (The 9.69 kΩ is just a variable resistance to modify the output frequency.)

Why is my op-amp pulse generator (LF353) delivering way less voltage (±2 V) than the voltage supplies of the amplifier (±15 V)?
I had to design the following circuit as a pulse generator so that if I vary the resistance the frequency will vary as well. It's defined by the frequency expression:
$$f=\frac{1}{2R_4C_1\ln(3)}$$

Relationship between pulse forward current vs pulse duration
I'm having trouble understanding why this application note for this proximity sensor suggests reducing the current for the IRED depending on the on time pulse duration. What is the relationship ...

Multiplication of pulse trains
Suppose I have two pulse trains, with pulses some tens of nanoseconds apart and long (evenly spaced and equally for both of them). Each of the pulses has some amplitude \$v_n\$ in one train and \$v_n'\...

Output with programmable rise time
I am tinkering with a device to generate pulses for a measurement setup.
No need to buy it: Just wondering how one would implement it.
Idea:
Device generates a square-wave (Vpp and DC-offset) output ...

What component is needed to collect injector pulse?
I am planning to convert this pulse to a digital signal (apx. 5 V for MCU input) based on voltage level. The maximum voltage of this pulse is 12 V when the injector nozzle is closed and 0 V otherwise. ...

Why does a MOSFET or IGBT's surge current rating stop increasing with decreasing pulse width beyond a point, unlike thyristors?
Thyristor
The surge current rating of a thyristor increases as the width of the pulse decreases. For a single non-repetitive pulse, it's not uncommon for a thyristor to have a surge rating that is 10x ...
