Abstract:
This dissertation describes methods of mitigating radio frequency interference(RFI) in the frequency range 10-100 MHz, developing and evaluating coherent methods with which RFI is subtracted from the afflicted data, nominally resulting in no distortion of the underlying signals. This approach is of interest in weak signal applications such as radio astronomy, where the signal of interest may have interference-to-noise ratio much less than one, and so can be easily distorted by other methods. Environmental noise in this band is strong and non-white, so a realistic noise model is developed, with

The most known accelerator at CERN is the Large Hadron Collider (LHC), in which proton beams are accelerated to the highest energy in the world and then put in collision to probe into the heart of matter. However, the LHC top energy is gradually built up in a chain of accelerators of equal importance. Each machine boosts the energy of the particles beam, before injecting it into the next machine in the sequence. Since the quality of delivered beam from the injector chain determines greatly the overall performance of the LHC, studies are carried out to overcome eventual beam parameters limitati

博士<br>國立交通大學<br>電子物理系所<br>107<br>This dissertation presents the investigation of temporal dynamics and coupling effect in Nd:YVO4 and Yb:KGW lasers. We have realized low-repetition-rate nanosecond Nd:YVO4 lasers and high-repetition-rate femtosecond Yb:KGW lasers with the help of coupling effect. Mode-locked operation with the repetition rate of 48 MHz and pulse duration of 7.67 ps is achieved by employing an M-shaped multi-pass cavity. The mode-locked pulse width is tunable between 0.8 ns and 2.6 ns by exploiting internal coupled cavities with different optical lengths. The reflectivity of the

碩士<br>國立中山大學<br>電機工程學系研究所<br>93<br>The first topic of this thesis proposes a digital negative phase shifter circuit which generates a clock with adjustable negative delays (phase shift) in order to avoid multi-locking hazards. Arbitrary negative phase can be generated by using multiplexers and voltage variable delay cells to select the required phase shift. The proposed design is implemented by 0.35 um CMOS 1P4M technology. A single-shot locking method is adopted to reduce the locking time. Most important of all, the negative phase shifter is predictable and adjustable. The simulation results
