Abstract :
An investigation is made of the error due to truncated impulse response for the block mode or sectioning technique. The upper bound on the error in terms of the sectioning parameters is obtained and shown to be independent of block size; this results in a simpler approach to obtaining an optimal sectioning procedure.
