Lossy audio codecs may remove frequencies from the original recording that most people can't hear, around 20 Hz to 20,000 Hz. While that may help save on streaming bandwidth, it can cause problems, too. You may have experienced some side effects of file compression while you watch a show...
Additionally, different volcano types have widely varying eruption frequencies. Scientists generally use a more sensible criteria these days, though it's based mostly on subjective assessment. If the volcano is erupting or demonstrating activity in the form of earthquakes or gaseous emissions, it is ...
DTMF uses audio frequencies, so key presses can be used to play recognizable melodies. Since each button makes two tones and they do not directly line up to standard musical notes, it's not an exact correlation, though.
This gives the fibers different resonant frequencies. A specific wave frequency will resonate perfectly with the fibers at a certain point, causing them to vibrate rapidly. This is the same principle that makes tuning forks and kazoos work -- a specific pitch will start a tuning fork ringing, ...
The cumulative relative frequency is the running total or accumulation of the relative frequencies up to a particular value or category in a dataset. It is calculated by adding the relative frequencies of all the values or categories that are less than or equal to the current value or category...
[Wireless Router] What is DFS (Dynamic Frequency Selection) and how does it work on ASUS router? What is DFS channel? DFS is Dynamic Frequency Selection, which is a function of using 5 GHz WiFi frequencies that are generally reserved for radar, such as military radar, satellite communication...
(see, for example, Steve Guttenberg's articleHow do you like your headphone sound: Accurate or bassy?). Mass-market phones and earbuds may well be designed to emphasize bass frequencies—which is great if that's what you like and horrible if not. Beware of products that draw too much ...
Light waves also come in many frequencies. The frequency is the number of waves that pass a point in space during any time interval, usually one second. We measure it in units of cycles (waves) per second, or hertz. The frequency of visible light is referred to as color, and ranges fr...
Waves don't always zap through the air from transmitter to receiver. Depending on what kinds (frequencies) of waves we want to send, how far we want to send them, and when we want to do it, there are actuallythreedifferent ways in which the waves can travel: 1) By line of sight; ...
The reason you’ll normally need to get the two services together is because they use the same cable going into your home. On a landline, voice calls only use a small portion of the frequencies available (going up to 4kHz). Broadband internet is delivered using the higher frequencies that...
