  • Mass Spectrometry

    Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of charged particles. It is used for determining masses of particles, for determining the elemental composition of a sample or molecule, and for elucidating the chemical structures of molecules, such as peptides and other chemical compounds.

  • Maximum Acoustic Input

    Maximum acoustic input is the maximum sound pressure level the microphone can accept, or the clipping level of the microphone, dB SPL.

  • Medium earth orbit (MEO)

    Generally defined as an orbit above low Earth orbit (altitude of 2,000 kilometers (1,243 miles) and below geostationary orbit (altitude of 35,786 kilometers (22,236 miles)).

  • Membrane

    A membrane is the moving part of the condenser.

  • MEMS

    Microelectromechanical systems (MEMS) integrate mechanical elements and electronics all patterned on a silicon substrate with standard microfabrication techniques. Feature dimensions are on the order of 1 μm.

  • Microfabrication

    Microfabrication is the technology used to fabricate components on a micrometer-sized (or smaller) scale.

  • Micrometer

    A micrometer or micron (symbol μm) is one millionth of a meter or equivalently one thousandth of a millimeter.

  • Mixer

    Circuit block used to translate signals from one frequency to another.

  • Most Significant Bit (MSB)

    The most significant bit (MSB) is the bit position in a binary number having the greatest value, positioned in left-most position. The MSB can also correspond to the sign of a signed binary number in one or two's complement notation. "1" indicating negative and "0" indicating positive.

  • Multipath Propagation

    A transmission path anomaly that acts as a time-varying source of signal non-linearity. Multipath can distort or reduce a received signal to the point of unreliable reception. In television, multipath is manifested as image "ghosting".

  • Multiplyinh DAC (MDAC)

    Multiplying DACs provide a function whereby the reference voltage level can be varied over a specified voltage range and frequency. The transfer function is Vout = Vref x the digital word. Multiplying DACs can be used as digital attenuators, waveform generators, and for calibration control. 2-quadrant multiplication the means either the Vref or Vout will support a bipolar range; 4-quadrant multiplication means that both the Vref and Vout will support a bipolar range.

  • Multitone Power Ratio (MTPR)

    The spurious free dynamic range containing multiple carrier tones of equal amplitude. It is measured as the difference between the rms amplitude of a carrier tone to the peak spurious signal in the region of a removed tone.
