Any device that attenuates a signal, but especially an electronic device that reduces the amplitude of a signal
A device for reducing the amplitude of a signal
Device which reduces the signal flowing through a circuit, commonly found built-in to connectors in values of 10dB from 10dB to 60dB Translation: takes a very "hot" (loud) signal and makes it softer, so it doesn't overload the circuitry in question Also "Pad "
Electrical device used to vary signal strength
In prokaryotes 1) region of DNA at which regulation of termination of transcription occurs, which controls the expression of some bacterial operons; 2) sequence segment located between the promoter and the first structural gene that causes partial termination of transcription [DDBJ/ EMBL/ GenBank Feature Table] http: //www ebi ac uk/embl/Documentation/FT_definitions/feature_table html
An adjustable passive network that reduces the power level of a signal without introducing appreciable distortion
(a) a network that is used to reduce the amplitude of a signal Typically, this is accomplished with two resistors, one in series with the signal and another from the output of the first resistor to ground This attenuates the signal by an amount dependent upon the ratio of the resistor values (b) a device used to reduce the volume of an amplifier It goes between the amplifier and the speakers, allowing a non-master volume amplifier to be cranked up to full power without being overly loud, in order to get the desired overdrive tone from the amplifier
A device inserted into the electrical or optical path to lessen or weaken the signal
A loss device, making output power less than input power
A device or network that absorbs part of a signal and transmits the remainder with a minimum of distortion
A potentiometer (pot) that is used to lower the amplitude of the signal passing through it The amplitude can usually be set to any value between full (no attenuation) and zero (infinite attenuation) Pots can be either rotary or linear (sliders), and can be either hardware or "virtual sliders" on a computer screen
A silencing unit in air conditioning ductwork to reduce transfer of equipment noise, mainly from fans into a occupied space or to an exterior
A device used to reduce the level of a signal This can be a resistor network or a control on a piece of equipment
a circuit in a receiver or antenna tuner to decrease its sensitivity, measured in decibels, used in a situation when the desired signal is blocked by a very strong interfering signal
a passive device made up of a network of resistors used to reduce voltage, current or power (signal strength) delivered to a load
{i} device that reduces the amplitude of an electronic signal (Electronics)
used in e s r, the attenuation of the microwave power passing along a waveguide is achieved by means of a metal plate placed along the axis of the waveguide The degree of attenuation increases as the plate is moved away from the wall of the waveguide toward the center In IR and UV spectroscopy, the attenuator is a toothed comb, grid, or star arrangement introduced into one beam of a spectrometer, operated either automatically through an electronic servosystem, or manually to balance the radiation in both beams
a safety device consisting of an impact absorbing box mounted at the rear of the vehicle to soften the impact of a rear-end collision
A passive device that weakens a signal that passes through it The amount by which the signal power is reduced is usually expressed in decibels
A passive optical component that intentionally reduces the optical power propagating in a fiber
A component that reduces the magnitude of current, voltage, or power of a signal in transmission between points
A device for reducing or adjusting signal level A resistance with a sliding contact
A device used to increase the attuation of an optical fibre link, generally used to ensure that the signal at the receive end is not too strong
A filter with a continous gradual change from a specific density to clear glass, or from a heavier to lighter density Sometimes used to designate a Graduated Filter
an electrical device for attenuating the strength of an electrical signal
An arrangement of fixed and/or variable resistive elements used to attenuate a signal by a desired amount
A passive device used to reduce the signal strength in a system Available in many different mounting configurations
