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 is the maximum sound pressure level the microphone can accept, or the clipping level of the microphone, dB SPL.
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)).
A membrane is the moving part of the condenser.
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 is the technology used to fabricate components on a micrometer-sized (or smaller) scale.
A micrometer or micron (symbol μm) is one millionth of a meter or equivalently one thousandth of a millimeter.
Circuit block used to translate signals from one frequency to another.
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.
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".
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.
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.
