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 "
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
(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 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 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
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 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
