Abstract: In an adaptive transform coding system and/or and adaptive transform decoding system, coding efficiency in the case where a small number of quantized values having large absolute value are present, is improved. The adaptive transform coding system codes the small number of quantized values having large absolute values and other quantized values are coded separately. More particularly, the adaptive transform coding system includes a selector (6) discriminating the small number of quantized value having large absolute value from other quantized value, a pulse coding means for coding the small number of quantized values having large absolute values (8) and the pulse decoding means (16) for decoding the same, a coding means (7) for coding the quantized value other than those having large absolute values and a decoding means (15) decoding the same, and a synthesis means (18) for synthesizing the small number of quantized values having large absolute value and other quantized values.

Abstract: An energy corrector (105) for correcting a target energy for high-frequency components and a corrective coefficient calculator (106) for calculating an energy corrective coefficient from low-frequency subband signals are newly provided. These processors perform a process for correcting a target energy that is required when a band expanding process is performed on a real number only. Thus, a real subband combining filter and a real band expander which require a smaller amount of calculations can be used instead of a complex subband combining filter and a complex band expander, while maintaining a high sound-quality level, and the required amount of calculations and the apparatus scale can be reduced.

Abstract: A random number generating apparatus is equipped with a random number memory section in which a plurality of sets of random numbers, whose total energy R, has a fixed value are stored. N random numbers are generated on the basis of more than one set of random numbers read from the random number memory section, and further multiplied by a square root of (T×M÷R÷N) to obtain a random number sequence having a predetermined energy. A normalization coefficient S can be obtained with a simple process without any usage of the calculation of division and square root multiplication, thereby enabling a small-scale apparatus to be realized. Accordingly, the random number generating apparatus has a decreased scale in the circuit arrangement capable of outputting the random numbers having a predetermined energy.
