    The Malawi Broadcasting Corporation is a state-run radio and television company in Malawi.It was founded in 1964. It has two radio stations, Radio 1 and Radio 2, and transmits on FM, Medium Wave and Shortwave frequencies and Online and MBC 2 Malawi.

  3. Nominal power (photovoltaic) - Wikipedia

    en.wikipedia.org/wiki/Nominal_power_(photovoltaic)

    In the context of domestic PV installations, the kilowatt (symbol kW) is the most common unit for nominal power, for example P peak = 1 kW. Colloquial English sometimes conflates the quantity power and its unit by using the non-standard label watt-peak (symbol W p), possibly prefixed as in kilowatt-peak (kW p), megawatt-peak (MW p), etc.

  4. MW DX - Wikipedia

    en.wikipedia.org/wiki/MW_DX

    MW DX, short for mediumwave DXing, is the hobby of receiving distant mediumwave (also known as AM) radio stations.MW DX is similar to TV and FM DX in that broadcast band (BCB) stations are the reception targets.

  5. HVDC converter station - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter_station

    A single-phase, three-winding converter transformer. The converter transformers step up the voltage of the AC supply network. Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components. The insulation ...

  6. HVDC converter - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter

    The two-level converter is the simplest type of three-phase voltage-source converter [29] and can be thought of as a six pulse bridge in which the thyristors have been replaced by IGBTs with inverse-parallel diodes, and the DC smoothing reactors have been replaced by DC smoothing capacitors. Such converters derive their name from the fact that ...

  7. Direct-conversion receiver - Wikipedia

    en.wikipedia.org/wiki/Direct-conversion_receiver

    A direct-conversion receiver (DCR), also known as a homodyne, synchrodyne, zero intermediate frequency or zero-IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is identical to, or very close to the carrier frequency of the intended signal.

  8. Frequency changer - Wikipedia

    en.wikipedia.org/wiki/Frequency_changer

    A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current of one frequency to alternating current of another frequency. The device may also change the voltage , but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much ...

  9. Digital down converter - Wikipedia

    en.wikipedia.org/wiki/Digital_down_converter

    In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages. The process can preserve all the information in the frequency band of interest of the original signal.
