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.

Low power low speed pulse divider?

I have a digital input which receives irregular pulses. I want a circuit that takes that input and generates an output pulse for every 100 (or so) input pulse. The expected input speed is 10-300 Hz. I ...

IGBT pulse max current

If in datasheet it reads that an IGBT can handle a 1200A current pulse for 1ms, and can operate at 500A max at 25C and 320 at 90C, how would I calculate what kind of pulse can it handle for 2 or 3 ms? ...

Analog circuit for obtaining a phase shift of 1-2 s in an arterial pulse wave signal of period 1-2 Hz

I am trying to design an analog circuit using an operational amplifier to introduce a phase lag of the order of 1-2 seconds in an arterial pulse wave signal (photoplethysmogram or PPG for short) that ...

Dual Edge Detector without using IC

I tried to simulate (before building it) a double edge detector circuit that I found in this post. When I simulated it, I got a decent pulse when I closed the switch but when I opened it, I got a ...

What circuit allows me to drive positive kV level pulses to antennas and over spark gaps to earth ground?

Ideally I would like 0-6kV pulses with adjustable frequency, but I could settle for 4kV and 40kHz. Pulses should be sharp as possible. Someone suggested a PWM module with a mosfet inside and to drive ...

Problem generating two asymmetrical pulse waves

I am trying to generate two pulse waveforms with a on to off time ratio of around 40/60. The max amplitude is only 5 V however the switching frequency is quite high at around 100 kHz. The two ...

How are PCM signals put onto a wire?

I just want to get a sense of how digital data is physically transmitted over cables using protocols like USB or Ethernet. I've read that they use PAM signaling (USB4 uses PAM-3, Gigabit Ethernet uses ...
