"Wow" is slow speed (a few Hz) variation, caused by longer-term drift of the drive motor speed, whereas "flutter" is faster speed (a few tens of Hz) variations, usually caused by mechanical defects such as out-of-roundness of the capstan of a tape transport mechanism. The measurement is given in % and a lower number is better.
Measurement is usually made on a 3.15 kHz (or sometimes 3 kHz) tone, a frequency chosen because it is high enough to give good resolution, but low enough not to be affected by drop-outs and high-frequency losses. Ideally, flutter should be measured using a pre-recorded tone free from flutter.
Some analog tape manufacturers specify frequency responses up to 20 kHz, but these measurements may have been made at lower signal levels. [16] Compact Cassettes may have a response extending up to 15 kHz at full (0 dB) recording level. [17] At lower levels (−10 dB), cassettes are typically limited to 20 kHz due to self-erasure of the tape media.
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
If you don't have broadband, you'll need to try other steps to fix problems with a dial-up internet connection. An active internet connection is required to be able to access all the best that AOL offers. If you're using broadband (cable) internet and you can't connect, try the following troubleshooting steps in the order listed until you get ...
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
Each test measures the data rate for the download direction, i.e. from the server to the user computer, and the upload data rate, i.e. from the user's computer to the server. The tests are performed within the user's web browser or within mobile apps. As of 17 February 2024, over 52.3 billion Internet speed tests have been completed. [8]
