For example a 3 digit PIN or combination lock has 1,000 possible values and so has almost 10 bits of entropy, because 10 bits allows you to count up to 1,024. The entropy of a password or encryption key can be used directly to estimate how long it might take to crack, by trying all possible values." current

In an audio system, a high S/N ratio tells you that any background hiss will be imperceptible, and in data communications, the S/N ratio directly affects the rate at which you can transmit data." current
• 21:1421:14, 19 February 2024 diff hist +355‎ N Glossary:Decibel ‎ Created page with "Decibels (dB) are a measure of relative power, for example by what factor does an amplifier increase the power of a signal, or by what factor is a TV signal reduced by losses in the cable between the aerial and the receiver. It's a logarithmic scale, 3dB representing a doubling of power, hence the dB gains or losses in a signal path can simply be added."
• 17:5217:52, 19 February 2024 diff hist +315‎ N Glossary:Noise ‎ Created page with "Noise, in the context of electronics and communications, is any unwanted interference tending to mask a desired signal. It can never be eliminated entirely as the electronics we're surrounded with all generates a certain amount of interference, and an electric current itself consists of a random flow of electrons." current
• 17:4017:40, 19 February 2024 diff hist +372‎ N Glossary:Metadata ‎ Created page with "Metadata is "data about data". For example, a document or spreadsheet may contain information about the author; a digital camera will normally embed information about the exposure, location, date and time of a photo. Sharing these or other types of file can result in undesirable information leakage and privacy issues if you're not aware of the metadata they may contain." current

"Decoupling capacitors" are commonly connected to a supply at various points in order to absorb these variations and minimise any such unwanted and detrimental couplings." current

The output voltage will be maximum if you draw hardly any current, and if you draw as much current as you can the output voltage will drop almost to zero. In either case the power delivered (voltage × current) will be minimal. An MPP or Maximum Power Point controller or inverter will continuously adjust the current drawn in order to maximise the power, for exam..."

A phase difference is measured in degrees; 360 degrees represents a complete cycle so is the same as no phase difference, whereas with a phase difference of 180 degrees, the peak of one wave will coincide with the trough of the other and combined, they will cancel out." current
