Is an electric guitar "analog"?
Kind of an odd question, I suppose.
I'm not sure if the magnetic pickups in a typical electric guitar qualify as being analog the same way that a magnetic tape recorder does. |

They produce an analogue signal which varies with the movement of the strings. The only vaguely non-analogue thing about them is the way that the output frequencies vary in more or less discrete steps, unless you've bent the pitch...... You *can* buy an electric guitar with a built in ADC connected to the pickup, which will then plug into a USB port directly. -- Tciao for Now! John. |

Yes, they have to be analog. Now, they could digitize the signal right there, on the spot, with an on board A to D converter. but the original source, and magnetic pickup has to be analog. |

They produce signal in exactly the same way a tape head does; changing magnetic fields induce a current into the coil of wire. Nothing quantized, no numbers, no samples. What could be more analog? (Unless you're reading notes, of course. Those are quantized. But then, the best way to get a guitar player to quit playing is to put sheet music in front of him.) Peace, Paul |

It's not digital because nothing is being quantized in time, therefore it must be analogue. 2. It's not analogue because the signals are quantized in amplitude (because they are represented as integer numbers of individual electrons with fixed charge), therefore it must be digital. 3. You play it with your digits, therefore it's digital. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

It's analog, but too often the signal is sent through excessively high gain resulting in hard clipping, effectively making it 1-bit amplitude sampled. |

Time has also been discovered to have a frequency, so is a series of still versions, essentially.

If you believe something without understanding it... what can I say? By the way, I have never heard of evidence for the speed of light being quantized. |

Once they are quantized by _amplitude_ or by time? Because you can have an analogue level quantized by time (PWM for instance)... By the way, I have never heard of evidence for the speed of light being quantized. As far as I know it's continuous and depends on the medium the light is passing through. But my knowledge of physics stops around special relativity. --Scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Digital means "represented by numbers", while quantized means having a discrete set of possible states. And what is the difference? There is none. The number of different numbers within any finite range goes to infinity as their precision increases. Having a discrete number of possible states implies a finite and bounded number of possible values in any finite range. |

C isn't the speed of light, per se. The speed of light changes all the time, it's what makes lenses work. It is different in different media. The constant C changing is different than the speed of light changing. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

bucket-brigade device reverb/flanger (which needs anti- alias and reconstruction filters) is analog? BINGO! Absolutely correct. You get it. Just to clarify a point peripherally raised by Mr Bradley's response... You can find books and magazine articles which state (or imply) that time-sampling a signal makes it digital. This is, of course, INCORRECT. All digital systems require some form of time-sampling (how can you set a specific value for wiggling Jell-O?), but one can have a sampled-data system that isn't digital. "Digital" means that sampled data are quantized -- and that's all. |
