what is aperture error?

The Liquid Crystal Display paragraph, while relevant, seems out of place in the intro paragraph of a device with a very broad range of uses in DAC. I've moved it to the Purpose section. — Preceding unsigned comment added by 128.151.150.17 (talk) 16:46, 8 October 2014 (UTC)Reply

"A typical sample and hold circuit stores electric charge in a capacitor and contains at least one FET (field effect transistor) switch and at least one operational amplifier" Seems quite a bold statement - various bipolar implementations also exist?

Have changed it to "a switching device". BBCLCD (talk) 20:51, 9 January 2017 (UTC)Reply

One of the best-known uses for Sample and Hold is as a musical synthesizer module in traditional analog synthesizers. This produces a sound which is held at a certain pitch or timbre for a period of time and then moves to another fixed setting. The different fixed values can be random (with a noise input for control) or stepped sequentially in pattern (by an oscillator.)

Probably the most common musical use of this module is for the stereotypical "computer" sound used in science fiction movies. This is a random series of pitched tones which was used to suggest that a computer was "working" on a problem. — Preceding unsigned comment added by 101.110.25.21 (talk) 07:31, 14 April 2017 (UTC)Reply

Supposedly Ben Burtt used his ARP 2600's sample and hold circuit, plus the output lag control and some other magic, to make R2D2's electronic voice, but I can't find a decent source. It's the kind of esoteric thing that only gets in-depth coverage on blogs, not newspapers. -Ashley Pomeroy (talk) 19:43, 10 August 2020 (UTC)Reply

Given that the musical effect is the most common meaning of the phrase "sample and hold", this article ought to at least mention it. I'll have to look around for a good source, but my understanding is that it is often used to make audio sound purposefully more "digital" by decreasing the effective sample rate.
