Title: FET band limited amplifier
Inventor: MIYAGI HIROSHI
IPC: H03F3/193
Filed: 2002-02-21
Granted: 2003-03-11
Abstract: It is object to provide an FET band limited amplifier capable of obtaining high gain. An FET band limited amplifier 5 included in an AM receiver comprises, for examples, five-stages amplifiers 11 through 15, and a BPF 16 inserted midway between them. Each of the amplifiers 11 through 15 operates as a differential amplifier using p-channel FET as an amplification element. The BPF 16 passes a band component broader than an amplification band of the entire FET band limited amplifier. A 1/f noise can be reduced by removing a low-level component of a signal amplified by the three amplifiers 11 through 13. A thermal noise can be reduced by removing a high-level component of a signal amplified by the three amplifiers 11 through 13. Therefore, each of the amplifiers 14 and 15 connected at the BPF 16 subsequently is not saturated with a noise component.

Filed: 2002-04-16
Granted: 2003-04-01
Abstract: The present invention provides a method to determine the image quality in real time, which comprises the steps as follows. When the brightness of pixels on both sides of a pixel among the one-dimensional pixels of an image picture is less than the brightness of the pixel for a specific amount, the brightness of said pixel is determined to be the wave peak. When the brightness of pixels on both sides of a pixel among the one-dimensional pixels of an image picture is larger than the brightness of the pixel for a specific amount, the brightness of said pixel is determined to be the wave valley. In addition, the brightness of edge pixels among the one-dimensional pixels of an image picture is not determined to be the wave peak even if it is the maximum. The brightness of edge pixels among the one-dimensional pixels of an image picture is not determined to be the wave valley even if it is the minimum. When the number of wave peaks/valleys of the image picture meets the requirement, it is determined whether the image picture is a good image picture; otherwise it is determined whether the image picture is a bad image picture.
