#oscillators

2025-01-17

A tiny way to compute a square / triangle wave at the same time without conditionals, only basic arithmetic and shifts.

This can be used for #oscillators or animations etc. #algorithm is a variant of HAKMEM 149.

Can also be used to draw a square. (And other shapes, see previous toot)

Code also shows how to draw a diamond shape by rotating the square by 45°.

There are two versions, optimized for size and optimized for speed.

Square wave and triangle waveform computed without conditionals, only basic arithmetic and shifts using HAKMEM 149 algorithm variants. Also show 2D shapes (square and diamond) drawn by combining the triangle and square value.p5js code of the algorithm optimized for size (has overdraw !)p5js code of the algorithm optimized for speed, the render code is moved outside the algorithm iteration loop, has much less overdraw except on the square wave code which is unchanged due to the sharp transition.

Neuronal dynamics can be
without the need of strong external currents, as usually assumed, here with A. Politi we explain how this can work thanks to term (open access article 2024)

In ancient times, people built some rather large and elaborate contraptions for measuring and reacting to the passage of time.

The discovery of electricity and the invention of electronics made this task dramatically easier. Instead of a big, unwieldy mechanical device, a simple electrical circuit could be used to generate a periodically oscillating signal.

Numerous devices, including radio, television, and computers, were made possible by these electronic #oscillators.

#Nanomechanical #oscillators could be used to build ultrasensitive sensors and to test macroscopic quantum phenomena. A scheme offers potential for order-of-magnitude improvements, the researchers say. #nanotechnology

GVST GSinth2 is a free VST synthesizer plug-in.

It has 3 oscillators with independent settings that can be used to create interesting sounds. Randomize buttons allow for quick experimentation with sounds.

Trying a comparison between a 7.3728Mhz quartz crystal and an Epsom 6Mhz oscillator.
The yellow is the double inverted 6Mhz (using a 74LS04), the blue is the raw 6Mhz out and the green the quartz crystal hooked up to two inverters as per Grant Searle's Z80 minimal chip count computer circuit.

The crystal doesn't look right...?

If you like #dynamicalsystems , #oscillators and #synchronization, do not miss the latest preprint by Iván León and Hiroya Nakao: arxiv.org/abs/2308.02105 Here they present a method to approximate a limit cycle through an expansion of the phase response curve, which seems to be very general.

I asked Iván a pair of years ago if one could do something like this, because I was interested too. Great to know he got a nice solution to the problem!

Here's a short explaining the effect on the #period of two #simple #harmonic #oscillators if you take them to another planet. Based on A Level physics question from AQA Paper 1 2021

No pleasant harmonies, just hard-substantiated NOISE! Spiraling at a sickening rate with fevered, crusty experimental noise, oozing oscillators and severe analog synth punishment from Romanian sound torturers UBURGRUND.

Did you see my second #modularsynthesizer #patch went live? This week we actually create a #synth that I would use in my own music. Chaotic #modulation, full rectification, fat stacks of square #oscillators and more. If you're curious about #modular, check it out.

Mastodetiquette seems to suggest I introduce myself, so... By day I'm a figure skating music editor @skatingmusicguy, in my spare time I make using and . My album (radiophonic 1970s-ish soundtrack to the book) came out on 2018, digital 2019, and on vinyl v soon!
