A Precision Calibration Solid State Noise Source with smooth Spectrum
نویسندگان
چکیده
Abstract—A Solid state calibration noise source for precision radio astronomy receivers has been designed built and tested. The Noise source has flat output noise spectrum, stability in time and frequency (smooth response), very low power dissipation, excellent power match...all on a very compact package that can easily be integrated with a radio astronomy receiver. The noise source has an integrated precision temperature sensor to measure the physical temperature during the “cold” state.

XAS measurements were performed at beamline E4 at the Hamburger Synchrotron Strahlungslabor (HASYLAB) under ambient conditions at 293 K. A Si(111) double crystal monochromator was used for measurements at the Cu K-edge (8.979 keV). The second monochromator crystal was tilted for optimal harmonic rejection. The energy resolution for the Cu K-edge energy is estimated to be 3.0 eV. The spectra wer...
متن کاملScintillation noise power spectrum and its impact on high-redshift 21-cm observations
Visibility scintillation resulting from wave propagation through the turbulent ionosphere can be an important source of noise at low radio frequencies (ν 200MHz). Many low-frequency experiments are underway to detect the power spectrum of brightness temperature fluctuations of the neutral-hydrogen 21-cm signal from the Epoch of Reionization (EoR: 12 z 7, 100 ν 175 MHz). In this paper, we derive...

متن کاملSynthesis of Single-Crystalline Octahedral Co3O4 with Solid-State Thermal Decomposition
In this paper, single crystalline octahedral Co3O4 with dimensions about 100–500 nm and smooth surface has been prepared by solid-state thermal decomposition of cobalt(II) Schiff base complex Co((3,4-MeO-ba)2 en)Cl2 as new precursor at 450ºC under air atmosphere for 3.5 h. Surface morphology of the products were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder ...
متن کاملA Unique Approach of Noise Elimination from Electroencephalography Signals between Normal and Meditation State
In this paper, unique approach is presented for the electroencephalography (EEG) signals analysis. This is based on Eigen values distribution of a matrix which is called as scaled Hankel matrix. This gives us a way to find out the number of Eigen values essential for noise reduction and extraction of signal in singular spectrum analysis. This paper gives us an approach to classify the EEG signa...
