| 149098 | 2003-06-01 13:18:00 | To a Email group called the CIN list, I made a posting about a project from May 2003, Silicon Chip on a Sine/Square Function Generator. Some no hoper said "I don't need that I can do it all with my computer" have a look at electronics.alternatezone.com if you can generate 1Hz to 10MHz in 1Hz steps Sine/Square only using a computer program then I will eat my hat., |

| 149099 | 2003-06-01 13:27:00 | Oh sorry I forgot the biggest joke, the dreamer thinks he can get 10MHz from a computer sound card?? | E.ric (351) | ||
| 149100 | 2003-06-02 01:38:00 | I'm with you E.ric. I can't do the math, but to get a 10MHz square wave I think you need just a little more bandwidth and a flatter HF response than an audio card can provide.:p However, dreams are free so allow your annoying correspondent to keep his illusions. Cheers Billy 8-{) [pre][b]Of course you could always ask politely for the program and output delivery method he intends to use. ?:| |

| 149101 | 2003-06-02 03:51:00 | Yes I am inclined to agree it is a pretty tall ask from a soundcard. | ikon (3923) | ||
| 149102 | 2003-06-02 05:50:00 | There is a soundcard interface project in the August 2002 Si Chip, "You can have a virtual electronics lab in your PC. Just attach this simple interface to your sound card". Typical soundcard frequency response is quoted as 20Hz to 20kHz. That is just a wee, wee bit short of 10Mhz, just a tad. :) |

| 149103 | 2003-06-03 03:05:00 | Electronics Australia a few years ago had a series using some nice chips in computer controlled signal sources . But that was a bit more sophisticated than a sound card . Of course square is easy to generate with TTL . . . sine is a bit more difficult, though with modern filters it might not be too bad . A PIC based unit might get a bit more than 1 MHz . My favourite PC port for things like that is a bit slow : printer ports start to run out of steam at aboput 100 kHz . , othewise a Disney Sound Source might be a good candidate . :D |
