摘要： A subband synthesis filtering apparatus for M sets of signals is provided. Each set of signals includes N subband sample signals. The apparatus includes a processor for processing the ith set of signals among the M sets of signals, wherein i is an integer index ranging from 0 to (M−1). The processor includes a DCT converting module and a generating module. The DCT converting module converts the N subband sample signals of the ith set of signals into N converted vectors. If i is an odd number, the (2j−1)th subband sample signal among the N subband sample signals is multiplied by negative one in the converting module, whereinj is an integer index ranging from 1 to (N/2). The generating module generates N pulse code modulation signals based on the N converted vectors.

摘要： The present invention provides a sensor alignment method using in a scanning apparatus. Firstly, providing a housing on the transparent board and defining a alignment area below the housing, the sensor locates under the alignment area and the light source locates aside the alignment area; then, moving the sensor out of underside of the alignment area and measuring intensity of light source to obtain a regional position where the brightest position on the transparent board, and moving the sensor to underside of the regional position; and finally, moving the sensor and the light source into the alignment area, and synchronously moving the sensor and the light source out to capture images. This invention prevents the tolerance formed in the printing process and the alignment point determination of the sensor is more precise, and furthermore, the scanning area is increased and the manufacturing cost is reduced.
