Inventor: DENT PAUL WILKINSON
IPC: H04L27/22
Filed: 1991-09-05
Abstract: A zero-IF radio receiver eliminates DC offset without distortion or loss of the low-frequency and DC components of the received or desired signal by initially differentiating the received signal to filter out the DC offset. The signal is amplified to a suitable level and then integrated to recapture the original DC and low frequency signal components. The integration essentially restores the filtered components to the original value in the amplified signal using an arbitrary constant of integration of bounded magnitude to generate a restored signal. Using various techniques that exploit predetermined signal patterns or inherent signal properties of the desired signal, the DC offset can be reasonably estimated. The DC offset estimate is then subtracted out of the restored signal leaving the amplified, received signal substantially free from distortion. An advantageous method for differentiating and digitizing the received signal uses the technique of companded delta modulation.

Abstract: Disclosed is a surface treating method of irradiating a beam of energy particles on a solid surface for forming an extremely thin compound film thereon, and then removing the compound film from the solid surface, thereby making it possible to etch the solid surface in order of atomic layer. For example, one or several atomic layers on the solid surface are selectively oxidized, and the resultant oxide film is removed from the solid surface. By repeating such processes, it is possible to etch the solid surface in order of atomic layer. The oxidation of the solid surface is performed, for example, by supplying an oxygen molecule thermally excited on the solid surface. The removal of the oxide film from the solid surface is performed, for example, by supplying a hydrogen fluoride (HF) gas on the oxidized solid surface. Since the interface between a semiconductor substrate and the oxide film formed on the surface thereof is made sharp in the atomic scale, it is possible to etch the solid surface in order of atomic layer by repeating the surface oxidation and the removal of the oxide film according to the above method.
