Abstract
PURPOSE: To eliminate dispersion in precision by simple constitution by digitally processing many impulse responses by using a memory unit.
CONSTITUTION: Impulse responses, collected by microphone 4-1, are sampled by basic clock pulse C-1 from timing control circuit 20 and then inputted to A/D converter circuit 7 to obtain a digital signal, which is inputted to accumulator 9 by way of square-law circuit 8. Accumulator 9 accumulates sequentially digital signals at the timing of signal C-1 and its output is added to the contents of register 12 by adder circuit 11 through register 10 at the timing of signal C-3, so that its result will be stored at a fixed address of RAM14 at the timing of signal C-4 and also inputted to register 13. The contents of RAM14 are inputted to register 12 at the timing of signal C-2. This process is repeated as to microphones 4-2 to 4-n to eliminate dispersion in accuracy at every measurement point.
