Abstract: ABSTRACT    Methods  and  compositions  for producing  materials  which exhibit  high  temperature  superconductivity.    The  material produced using the present invention is high in purity and is able to exhibit superconductivity at temperatures above those obtainable by liquid nitrogen.  The present invention discloses techniques for fabricating ceramic superconducting materials of the type having the general chemical formula MBa2Cu3O7-x, using an aqueous coprecipitation process.    According to the teachings of the present invention, the metal  components  of  the  superconducting  material  are  first placed in solution.  The ratios of the various components are carefully chosen so that  the final product has the desired stoichiometric ratio.    The solution pH is adjusted by the addition of a basic solution which contains only volatile components.  That is, pH is adjusted in such a manner that the pH adjustment does not leave residue of any type in the final superconducting product after  the product is heated,  sintered, or calcined.   Accor-dingly, ammonium hydroxide, ammonia gas and urea are generally preferred for adjusting the pH.

Title: Fading bit error protection for digital cellular multi-pulse speech coder
Inventor: ZINSER RICHARD L
IPC: G10L19/00
Filed: 1990-09-13
Abstract: RD-19,900 FADING BIT ERROR PROTECTION FOR DIGITAL      CELLULAR MULTI-SPEECH CODER       ABSTRACT OF THE DISCLOSURE      Protection of a digital multi-pulse speech coder from fading pattern bit errors common in a digital mobile radio channel is accomplished with error detection techniques which are simple to implement  and require no error correcting codes.  A synthetic regeneration algorithm is employed which uses  only  the  perceptually  significant  bits  in  the transmitted  frame.   Separate  parity  checksums  for  line spectrum pair  frequency data,  pitch  lag  data  and pulse amplitude data are added to each frame of speech coder bits in the transmitter.  The bits are then transmitted through a mobile environment susceptible to fading that induces bursty error patterns in the stream. At the receiving station, the parity checksum bits  and  speech coder bits  are used to determine if an error has occurred in a particular section of the bit stream.  Detected errors are flagged and supplied to the speech decoder.  The speech decoder uses the error flags to modify its output signal so as to minimize perceptual artifacts in the output speech.
