PURPOSE:To obtain a display data processing system which maintains a constant background noise level even when analysis conditions such as a frequency analysis width and an integration value are changed and displays a screen which can be viewed easily. CONSTITUTION:A display data processing device consists of a signal analyzer 1 which analyzes signal, a dispersion calculator 2 which obtains the dispersion value, a coefficient generator 3 which obtains a coefficient (= constant/ dispersion) for making constant a noise level, a multiplier 4 which multiplies an output of the signal analyzer 1 by a coefficient, and a display processor 5 which processes signal. By multiplying the analyzed signal by a coefficient which is obtained from a dispersion value of signal after analysis, the background noise level of the multiplied signal can be maintained to be constant and a background concentration is kept to be constant. |
