Rational Question: Analog Electronic Chip

Look up "op amp".

There is no such thing. (other than, possibly, some esoteric experimental lab devices.)

With a capacitor.

Maybe you should give your local public library a visit.

Good Luck! Rich

If there can be a digital storage chip, why can't there be the analog equivalent?

How about an analog sample-and-hold circuit? That stores data in the form of an analog voltage. I don't know if any are still being manufactured, since the shift to digitize-and-hold.

Bucket brigade analog shift register, storing and transporting kilosamples of analog data.

"Analog" and "digital," strictly speaking, refer only to means of encoding information. Circuits themselves are neither analog or digital, although those terms are very commonly used to refer to classes of circuitry or designs which are optimized for dealing with information encoded in one of these two forms. For example, what we commonly call "digital" electronics are simply those in which the active devices are, in normal operation, operating either in saturation or cut-off. Although there's been exceptions to that, too - take a look at the old "ECL" form of logic chips.

To the extent that information is stored in analog form (for instance, in the storage capacitor of each sub-pixel of an active matrix display), it's "stored" as a voltage or current.

"Sampled" does not necessarily imply "digital."

Maybe but that device posted in the link does seem to use PAM [Pulse Amplitude Modulation] which is neither digital nor analog but something in between. A true analog electronic chip-based storage device would simply store an electrical equivalent of the signal -- i.e. the electrical waveforms generated by the attched microphone as it picks up sound. A louder sound would result in a greater difference in voltages than a softer sound, and a higher-pitched sound would result in a more rapidly-alternating electric current than a lower- pitched sound.

Wow, Radium, you sure have some basic reading to do!

Where is it gonna "store" this "equivalent"? on a little reel of tape?

Eh, troll boy?

The Chipcorder MLS (multi Level Storage) voice recording chips use a form of analog storage I believe.

Dave.

In a chip that contains capacitors to store the electric charges of the AC current generated by the microphone when exposed to sound.

True. However, one set of capacitors can store a forward DC, while another set can store DC in reverse. So during "playback" the end result will be an AC current.

Oops, didn't follow that link in your original post, same thing.

Dave.

In all fairness to our pet net-kook, ths is one time when he has, (at least in IMHO), a reasonable point. PAM & PWM do, arguably, straddle the digital & analog domains. (That said, I won't be surprised if he takes this tiny bit of support as an endorsement for his other, totally whacky beliefs...)

Why do you think there is something "in between" analog and digital encoding? What, exactly, would that mean?

Bob M.

How are you going to arrange this "playback"? How will you arrange for it to happen more than once?

They are not, in my opinion, "beliefs". They are convenient tools with which he manipulates newsgroups. Radium is a classic troll, nothing more, nothing less. He does what he does for amusement. The longer he can spin this out, the more his infantile crippled ego will be gratified. If you view this group in Google Groups, click on "view profile" at the top of one of his posts, and see what other posts he has made recently. In particular, the "contribution" he made recently in alt.fan.mozilla, where he started a thread entitled "Mozilla is better than Firefox. Hail to Mozilla!". The post he made consisted of "Firefox is so creepy, frightening, disgusting, terrifying, irritating, and annoying." followed by this line -

Mozilla is better than Firefox!

- repeated 288 times with blank lines in between.

When the amount of attention he was getting began to flag, he posted this little gem:

"I still maintain:

Mozilla = the fresh, bright, warm, rejuvenating, refreshing aroma of sour red-&-green peaches

Firefox = stinky thick stinky foamy human diarrhea kakaa foam of a human who eats stale cheddar cheese and sticky milk chocolate and rotten lentils

Firefox stinks like stinky thick stinky foamy human diarrhea kakaa foam of a human who eats stale cheddar cheese and sticky milk chocolate and rotten lentils"

He has posted the rather revealing "kakaa foam" effort in other places too.

He managed to reel in enough suckers to create a thread 29 posts long!

He reminds me very much of an infant who thinks himself very clever for having retrieved some feces from his diaper and smeared it all over his nursery, and it is for that reason that I suspect that he has fairly pronuunced mental health and/or developmental issues.

Qbits?

In a similar way in which audio can be played back from a digital chip. Excepts its all analog and with no need for a carrier signal. The capacitors can store the audio permanenetly as long as new audio is not recorded over it. This is like a purely-analog RAM chip with only the modulation signal. No bits or samples. Just the electrical- equivalent of the sound waves that enter the attached microphone.
