  2. Super Famicom Naizou TV SF1 - Wikipedia

    en.wikipedia.org/wiki/Super_Famicom_Naizou_TV_SF1

    Unlike the earlier Sharp Nintendo Television, AV output terminals were made readily accessible on the SF1's extended terminal which allowed connection to later peripherals such as the Satellaview. The C1 had been notably unable to connect to the Family Computer Disk System , and the SF1's design was intended to alleviate this problem with any ...

  3. RF module - Wikipedia

    en.wikipedia.org/wiki/RF_module

    An RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data. Transmitter modules are usually implemented alongside a microcontroller which will provide data to the module which can be transmitted.

  4. Radio transmitter design - Wikipedia

    en.wikipedia.org/wiki/Radio_transmitter_design

    A radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. Radio waves are electromagnetic waves with frequencies between about 30 Hz and 300 GHz. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the ...

    Commercial FM broadcasting transmitter at radio station WDET-FM, Wayne State University, Detroit, US.It broadcasts at 101.9 MHz with a radiated power of 48 kW.. In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal ...

  6. Software-defined radio - Wikipedia

    en.wikipedia.org/wiki/Software-defined_radio

    Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system.

    VF14 – Sharp-cutoff pentode, 55 V heater, Y8A 8-pin steel tube base, identical to EF14 and UF14 except for heater ratings [2] VF14M – Selected VF14 in production until the end of the 1950s for use as a preamplifier in Neumann condenser microphones U-47 and U-48 where they were run at only half their rated heater power to reduce noise [ 58 ]

  8. Spark-gap transmitter - Wikipedia

    en.wikipedia.org/wiki/Spark-gap_transmitter

    A practical spark gap transmitter consists of these parts: [11] [13] [14] [15] A high-voltage transformer, to transform the low-voltage electricity from the power source, a battery or electric outlet, to a high enough voltage (from a few kilovolts to 75-100 kilovolts in powerful transmitters) to jump across the spark gap. The transformer ...

  9. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    The transmitter radiates a beam of microwaves into the sky, at a shallow angle above the horizon toward the receiver. As the beam passes through the troposphere a small fraction of the microwave energy is scattered back toward the ground by water vapor and dust in the air. A sensitive receiver beyond the horizon picks up this reflected signal.
