  2. RF Online - Wikipedia

    en.wikipedia.org/wiki/RF_Online

    RF Online, originally named 'Rising Force', (Korean: 라이징 포스) is a 3D MMORPG developed by CCR. The first version of the game was released in South Korea and was later followed by Chinese (Mandarin), Japanese, Indonesian, Portuguese and English translations.

  3. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic ...

  4. Non-return-to-zero - Wikipedia

    en.wikipedia.org/wiki/Non-return-to-zero

    The binary signal is encoded using rectangular pulse-amplitude modulation with polar NRZ(L), or polar non-return-to-zero-level code. In telecommunications, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented by some other significant condition, usually a negative voltage, with ...

  5. Radio receiver design - Wikipedia

    en.wikipedia.org/wiki/Radio_receiver_design

    The RF signal from the antenna may have one stage of amplification to improve the receiver's noise figure, although at lower frequencies this is typically omitted. The RF signal enters a mixer, along with the output of the local oscillator, in order to produce a so-called intermediate frequency (IF) signal. An early optimization of the ...

    SR connector (from Russian: Cоединитель Pадиочастотный) is a Russian RF connector, based on the BNC connector and which comes in a 50 Ω and 75 Ω versions; TNC connector (threaded Neill-Concelman) Twin-BNC (Twinax) Twinax connectors are used with 78 Ω or 95 Ω conductor cables and operate from 0–200 MHz. Due to ...

  7. RFIC - Wikipedia

    en.wikipedia.org/wiki/RFIC

    A radio-frequency integrated circuit, or RFIC, is an electrical integrated circuit operating in a frequency range suitable for wireless transmission. Applications for RFICs include radar and communications.

  8. Run-length limited - Wikipedia

    en.wikipedia.org/wiki/Run-length_limited

    Generally run length is the number of bits for which signal remains unchanged. A run length of 3 for bit 1, represents a sequence 111. For instance, the pattern of magnetic polarizations on the disk might be +−−−−++−−−+++++, with runs of length 1, 4, 2, 3, and 6.

  9. Absolute radio-frequency channel number - Wikipedia

    en.wikipedia.org/wiki/Absolute_radio-frequency...

    In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal. ARFCNs for GSM are defined in Specification 45.005 Section 2.
