PC Audio Frequency Meter |
|
|
This PC-based test-gear project covers slightly more than the full 20Hz to 20kHz of the audio range. Although the accuracy of the unit does not compare to a high-quality digital frequency meter, it still provides more than adequate results for many purposes, and it is certainly easier to use and more accurate than an analog frequency meter. The interface should work with any reasonably modern PC.
More details on this construction project can be found in the June 1999 issue of EPE Online, the world's first web-delivered electronics and computing hobbyist magazine. PURCHASE this issue or peruse more Projects |
