2. Symbol rate - Wikipedia

   en.wikipedia.org/wiki/Symbol_rate

   The carrier frequency is 1800 Hz, meaning that the lower cut off frequency is 1,800 − 1,200/2 = 1,200 Hz, and the upper cutoff frequency is 1,800 + 1,200/2 = 2,400 Hz. A V.34 modem may transmit symbols at a baud rate of 3,420 Bd, and each symbol can carry up to ten bits, resulting in a gross bit rate of 3420 × 10 = 34,200 bit/s. However, the ...

3. Bluetooth - Wikipedia

   en.wikipedia.org/wiki/Bluetooth

   Bluetooth operates at frequencies between 2.402 and 2.480 GHz, or 2.400 and 2.4835 GHz, including guard bands 2 MHz wide at the bottom end and 3.5 MHz wide at the top. [25] This is in the globally unlicensed (but not unregulated) industrial, scientific and medical ( ISM ) 2.4 GHz short-range radio frequency band.

   1.0 — Basic remote control commands (play/pause/stop, etc.) [6] 1.3 — all of 1.0 plus metadata and media-player state support [7] The status of the music source (playing, stopped, etc.) Metadata information on the track itself (artist, track name, etc.). 1.4 — all of 1.3 plus media browsing capabilities for multiple media players [8]

5. Irreducible fraction - Wikipedia

   en.wikipedia.org/wiki/Irreducible_fraction

   For example, ⁠ 1 / 4 ⁠, ⁠ 5 / 6 ⁠, and ⁠ −101 / 100 ⁠ are all irreducible fractions. On the other hand, ⁠ 2 / 4 ⁠ is reducible since it is equal in value to ⁠ 1 / 2 ⁠, and the numerator of ⁠ 1 / 2 ⁠ is less than the numerator of ⁠ 2 / 4 ⁠. A fraction that is reducible can be reduced by dividing both the numerator ...

   en.wikipedia.org/wiki/LHDC_(codec)

   Low Latency High-Definition Audio Codec (LHDC) is an audio codec technology developed by Savitech.LHDC allows high-resolution audio streaming over Bluetooth.It is a high-quality Bluetooth codec based on the A2DP Bluetooth protocol and allows a bit-rate of up to 900 kbit/s compared to SBC's bit rate of 345 kbit/s .

9. Bluetooth Low Energy - Wikipedia

   en.wikipedia.org/wiki/Bluetooth_Low_Energy

   Instead of the classic Bluetooth 79 1-MHz channels, Bluetooth Low Energy has 40 2-MHz channels. Within a channel, data is transmitted using Gaussian frequency shift modulation, similar to classic Bluetooth's Basic Rate scheme. The bit rate is 1 Mbit/s (with an option of 2 Mbit/s in Bluetooth 5), and the maximum transmit power is 10 mW (100 mW ...
