Attenuators
... An attenuator is a device for introducing a specified loss between a signal source and a matched load without upsetting the impedance relationship necessary for matching. The loss introduced is constant irrespective of frequency; since reactive elements (L or C) vary with frequency, it follows that ...

... The impedance of a low-pass filter should be about the same as the impedance of the transmission line into which it is inserted. (G7C06) The effect of lead inductance in a capacitor used at VHF frequencies and above is that effective capacitance may be reduced because of the lead inductance. (G6 ...

... both transformers and limits the accuracy of the measured impedance. The influence of initial voltage can be partially decreased by shielding both transformers. Further reduction of error due to initial voltage can be achieved by measuring and subtracting its amplitude and phase from phasor of total ...

... The component or circuit will not have the same impedance at all frequencies. It is common for inputs and outputs on many types of equipment to have their impedances quoted in Ohms and to assume a common frequency for that particular type of equipment. For example, audio commonly uses a frequency of ...

... An ideal filter will pass all frequencies in a given band without (attenuation) reduction in magnitude, and totally suppress all other frequencies. Such an ideal performance is not possible but can be approached with complex design. Filter circuits are widely used and vary in complexity from relativ ...
