31. Attenuators placed along the RF circuit prevent the reflected wave from traveling back to the cathode.32. While an amplifier provides gain, an attenuator provides loss, or gain less than 1. 33. Basic circuits used in attenuators are pi pads ( ?-type ) and T pads. 34. The cabinet cover includes accessories such as an impedance adapter, fixed attenuator and antenna simulator. 35. Accuracy here depends on the accuracy of the attenuator and not at all on the detector. 36. For this T to Pi conversion, see the equations in Attenuator ( electronics ) ). 37. The attenuator was installed in 1992 after three crashes against the pit wall from 1986-91. 38. A company then makes a custom ear-piece into which different attenuator capsules can be inserted. 39. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. 40. In the example practical chain shown above there is a 22 dB attenuator required in the chain.
