The authors cover periodic structures in electromagnetics, planar periodic structures as electro magnetic bandgap surfaces, compact planar periodic structure as band-rejection filter, and many other related subjects.
This RX bandpass filter can be replaced by a TX band-rejection filter. Similar to the operation of the TX intermodulation distortion cancellation loop, the RX noise signals through the RX bandpass filter are adjusted by a variable attenuator ([A.sub.3]), a phase shifter ([[phi].sub.3]) and an error amplifier 2.
Uses of the low-frequency, high-frequency, band-pass and band-rejection filters allows for allocating the ranges of frequencies relevant to the AE diagnostic signal.
