Abstract
A resistor of a specific resistance value is inserted between a signal line for transmitting ionization chamber current and a logarithmic amplifier. The specific resistance value is selected to be a proper value so that the value of a negative feedback capacitance of the logarithmic amplifier can be made zero or extremely small without instability phenomena such as an overshoot, ringing or oscillation. Accordingly, it is possible that the response time of a logarithmic measuring apparatus is extremely reduced in a small input-current region.
