41. The values of resistance of the attenuator 's elements can be calculated using image parameter theory. 42. To minimize loading, attenuator probes ( e . g ., 10X probes ) are used. 43. An "'attenuator "'is an electronic device that reduces the distorting its waveform. 44. Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. 45. The speakers can be further subdivided into zones with the use of multiple attenuators attached to each amplifier. 46. Attenuators have a flat frequency response attenuating all frequencies equally in the band they are intended to operate.47. A vertical input goes to a frequency-compensated step attenuator to reduce large signals to prevent overload. 48. TriQuint's GaAs and attenuators , Bessel filters, and low-noise amplifiers ( LNA ). 49. The impedance of the diode is different during the two states, so an output attenuator is used. 50. Dr . Talbot referred to the energy-absorbing tire piles as " spherical elastic attenuators ."
