456 monitor system • monovalent
program runs and inputting or outputting data to
or from memory. Also called executive program.
monkey chatter The characteristic sound of a single-sideband
(SSB) signal when the receiver is
mistuned, or when the receiver is set for the
wrong sideband.
monk’s cloth A coarse drapery fabric sometimes
used to soundproof the walls and ceiling of a radio
studio or recording booth.
mono See MONAURAL.
mono- Prefix meaning single.
monobrid circuit An integrated circuit in which
either several monolithic IC chips are interconnected
to form a larger, single-package circuit, or
monolithic IC chips are interwired with thin-film
components into a single-package circuit. The
name is a contraction of monolithic hybrid.
monochromatic 1. Being of one color (hue) in nature.
2. Being of a single wavelength in nature
(pertaining to radiation of any kind). 3. Pertaining
to black-and-white television.
monochromaticity Consisting of one color of visible
light. The brightness can vary from black to
maximum.
monochromatic power density At a given temperature,
the energy radiated per square centimeter
of blackbody surface per second per unit
wavelength range. Also see BLACKBODY and
BLACKBODY RADIATION.
monochromatic sensitivity Sensitivity to light of
one color only.
monochrome television Black-and-white television.
monoclinic crystal A crystal having three axes of
unequal length; two of them intersect obliquely
and are perpendicular to the third [e.g., the type
of crystal found in one form of sulfur (monoclinic
sulfur)].
monocrystalline material See SINGLE-CRYSTAL
MATERIAL.
monode A one-element device, such as a filamenttype
lamp, thermistor, voltage-dependent resistor,
barretter, etc.
monogroove stereo A method of making a stereophonic
phonograph disc in which both channels
are recorded as a single groove.
monolayer A thin film having a thickness of one
molecule.
monolithic integrated circuit An integrated circuit
(IC) formed in a single block or wafer of semiconductor
material. The name is derived from the
Greek monolithos (“one stone”). Compare HY-
BRID INTEGRATED CIRCUIT and THIN-FILM IN-
TEGRATED CIRCUIT.
monometallic Containing or using only one metal.
monomolecular film See MONOLAYER.
monophonic recorder See SINGLETRACK RE-
CORDER.
monophonic system A single-channel sound system.
Compare STEREO SYSTEM.
monopole antenna See QUARTER-WAVE MONO-
POLE.
monopulse In radar and electronic-navigation operations,
using one pulse to determine azimuth
and elevation simultaneously.
monorange speaker A loudspeaker that reproduces
most of the full audio range. Also called extended
range speaker. Compare TWEETER and
WOOFER.
monostable Having one stable state.
monostable blocking oscillator Abbreviation,
MBO. A blocking oscillator that behaves somewhat
like a one-shot multivibrator. The oscillator
delivers a single output pulse each time it receives
an input (trigger) pulse.
monostable multivibrator A multivibrator that
delivers one output pulse for each input (trigger)
pulse. Also called one-shot circuit and single-shot
multivibrator. Compare ASTABLE MULTIVIBRA-
TOR and BISTABLE MULTIVIBRATOR.

monostable multivibrator
Output
monostatic reflectivity The property whereby, for
certain reflectors (such as a tricorner reflector),
all incident rays are reflected in exactly the opposite
direction from which they arrive.
monotone A sound or series of sounds having a
single, constant pitch (frequency).
monotonicity In a digital-to-analog converter, a
condition where the output either remains the
same or increases for any single increase in the
input code.
monovalent See UNIVALENT.
