Abstract
PURPOSE: To efficiently average only sample signals, by storing an atomic nucleus's free damping resonance signal into an analogue memory to perform necessary compensation and thereafter effecting A/D conversion for Fourier transformation.
CONSTITUTION: An atomic nucleus' free damping resonance signal generated by a magnetic resonance device is stored in the analogue memory 13 of an operation processor 8 until a following signal is entered. The stored signal is passed through a mixer 14 and changed into a digital signal by an A/D converter 10. A CPU11 picks out only a solvent signal or the like from the digital signal and applies the picked-out signal to the mixer through a D/A converter 16 and a switch 15. The CPU performs subtraction or the like of a signal from the memory 13 and removes an unnecessary solvent signal or the like to execute compensation. The memory 13 and the mixer 14 are used as signal transmission lines to perform integration or the like of numerous free resonance signals to average them. Only the sample signals are thus efficiently averaged to perform accurate Fourier transformation.
