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 ...

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:
$$f=\frac{1}{2R_4C_1\ln(3)}$$
...

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 ...

Reducing the signal frequency
I have a sawtooth signal: roughly speaking, the duration of the "tooth" is 1 ms. Is it possible in the analog world to thin out this signal? For example, leave only every third, tenth "...

Peak/envelope detector circuit for 30 MHz sine pulses with a 10 kHz PRF
My goal is to input 30MHz sine pulses, with a pulse width of 10us and gap of 90us between the pulses. The circuit should convert this pulse train to a TTL signal that goes from 0 to 5 volts.
To ...

Square wave distortion on low frequencies
I have this old Soviet low frequency sine and square pulse generator "G3-36A".
I ran into an interesting problem.
When I try to generate square pulse under 100Hz I get a distorted wave. ...

Convert a continuous voltage to a pulsed voltage
I have a continuous 5V voltage which I would like to switch ON/OFF at a certain frequency. The output should be between 2V - 5V, and the minimum duration between ON/OFF should be 1 ms. The control ...

What electronic component can send pulses? [closed]
In analog hardware synthesizers, an electric pulse is sent by an oscillator to a sound-emitting device for it to create sound at the desired frequency.
What device generates this pulse?
What is the ...

Low-pass (band-pass) filter for op amp circuit
I have a circuit that amplifies a one-shot inductive trigger pulse of about 1.3Khz (@780 micro sec period) from about 10-200mV to about 3-4V. Between C1 and R3 there is a 0.13uH inductor coil with 11 ...

Does a RF frequency multiplier work with ultrashort pulse?
The question is, does a RF frequency multiplier work with ultrashort pulses?
In another words, does the frequency multiplier change the pulse width of input signal?
For example, suppose we have a ...
