Abstract:
Disclosed is a broadband log-periodic dipole antenna, which has first and second radiating elements alternately and symmetrically arranged in both surfaces of a dielectric substrate according to the corresponding PCS frequency band, IMT-2000 frequency band, and wireless LAN (IEEE 802, 11a/b) frequency band, so that the first and second radiating elements are alternately supplied with signals to make the impedance matching, thereby producing high gain in each of the resonant frequency bands and preventing the distortion of the radiating patterns owing to the broadband characteristics. The arrangement of the first and second radiating elements in both surfaces of the dielectric substrate considerably also reduces the size of the antenna, thereby facilitating mass production with low cost.
Abstract:
A digital camera for processing a digital signal. The camera includes an image signal processing circuit which uses a low-resolution analog-to-digital converter. The processing circuit performs AGC and gamma control on both digital and analog signals. Gain control and gamma control are performed by auto gain controllers which either process an analog signal prior to converting the analog signal to a digital signal or after the analog signal is converted to a digital signal. The image signal processing circuit performs processing based on the output of one of a m-bit output of an AGC/gamma controller and a m-bit output of an A/D converter. The AGC/gamma controller receives an n-bit clamped image signal from a clamper, while the m-bit A/D converter receives an analog input. This selection operation minimizes the need for a high-resolution A/D converter.
