How about square waves made from BLITs? That’s a standard approach. To hear the difference, try the test oscillator in Logic Pro. It has an anti-alias option to switch between a naive square / pulse wave, which is useful in some cases, since it has only 2 values, and a BLIT version, which

There's this preoccupation I have since the advent of going "digital", let's say since I heard music being played on CD in the early 80s. I grew up with access to electronics equipment that would generate "square waves" in some sorts of analogue fashion, including originally "digital" chips,

Hello Theo same as me :-) I played electronic organ sind 1982 and quicky started to modify it with own electronics. Later, I started with GALs and PLDs to create an own organ. The first concept was like this: http://96khz.org/htm/pldmodularorgan.htm A coarse DDS created from a digitally

Theo, My tl;dr answer to your question is it's difficult because even if it's digital, it's not digital. Ever. It's always analog. Like you, I'm a university EE (and Comp. Sci.) because I wanted to go into chip design. This was back in the early 80's. So maybe my classwork was different than

75th or 150th harmonics? A bandlimited squarewave of 8 kHz @ 44.1 kHz samplerate is a sinewave. 3 * 8 kHz is already outside of the bandwidth. This means that the basic frequency must be pretty low to get a square wave shape. - Uli 2018-06-13 20:40 GMT+02:00 robert bristow-johnson : > > >
