Title: Digital data interpolation device
Inventor: KOMAMURA TERUYA
IPC: G10L19/02
Filed: 1994-04-12
Abstract: PURPOSE:To provide the digital data interpolation device with a small arithmetic amount and with superior interpolation accuracy by dividing an input signal into plural sub-bands for interpolation. CONSTITUTION:An input signal is divided into M sub-bands by the 1st and 2nd analysis QMF 11 and 15. The sub band signals are reduced to the sampling frequencies by (the band width of a sub band signal)/(the band width of an input signal) by the use of decimation circuits 12, 13, 16, and 17 and are interpolated by interpolation circuits 18, 19, and 20. The interpolated sub-band signals are returned to the sampling frequencies of the original input signals by the use of interpolation circuits 21, 22, 25 and 26, combined by the use of the 1st and 2nd combination QMF 24 and 27 and returned to the original signals. Thus, the arithmetic amount can be reduced and the number interpolation samplings of respective sub-band is reduced, resulting in reducing the estimation degree and improving the interpolation accuracy.

Abstract: PURPOSE:To improve operability by starting DX search from a broadcasting station next to a broadcasting station under receiving when the search is disabled by LOCAL search excepting for the broadcasting station under receiving and long distance DX search is started. CONSTITUTION:A value N of the broadcasting station received just before the execution of a start operation is stored in a memory. Next, a mode is switched to a LOCAL mode, the value N applied from a microcomputer 9 to a PLL circuit 8 is updated, when the value is updated once through, reception is disabled in the LOCAL mode, and DX search processing is started. Concretely, it is judged whether the intensity of an electric field outputted from an intermediate frequency amplifier 3 through an S meter output line 3a to the computer 9 is larger than the search threshold value of LOCAL search or not. When the electric field intensity is larger than the threshold value of the LOCAL search, namely, when there is any broadcasting station which enables reception, the search operation is stopped at that time point, and this broadcasting station is received.

Abstract: PURPOSE:To obtain a proper threshold voltage having less scattering in a vertical shield base MOSFET, by a method wherein after each of semiconductor regions is formed, impurity ions for threshold voltage control are implanted through a gate oxide film. CONSTITUTION:Windows are opened on an N type substrate 1' by means of a photographic technique.

Similarly, regions 3, 4 are formed, and a gate oxide film 5 is formed. Through this film, boron ions for threshold voltage control are implanted with a concentration of 1-9X10<11>cm<-2> to form a P region with a surface concentration of 0.9-8X10<16>cm<-2>. Thereby, since the surface concentration in the threshold voltage controlling born ion implantation is almost on the same level with that in the high-dielectric strength low-concentration P type region forming boron ion implantation, a threshold voltage can be controlled, so that it is possible to obtain a proper voltage having less scattering.
