    • A device for counting the edges of electric pulses is disclosed and comprises a first capacitor connected in series with a pump circuit, which comprises a first resistance in series with a first diode connected in parallel with a second resistance, and a second capacitor connected in parallel with the first resistance. When a voltage, which is caused by one of the edges of an electric pulse, is applied across the first capacitor and the pump circuit, the first and second capacitors are charged in series with a charge that is essentially determined by the second capacitor. A first input of a comparator is connected to the connection point between the first capacitor and the pump circuit and a second input of the comparator is connected to a comparison potential, in order to indicate that a given approximate number of pulses have been counted when the voltage across the first capacitor exceeds a threshold level determined by the comparison potential.
    • 公开了一种用于对电脉冲的边缘进行计数的装置,并且包括与泵电路串联连接的第一电容器,其包括与与第二电阻并联连接的第一二极管串联的第一电阻和并联连接的第二电容器 与第一个阻力。 当由电脉冲的一个边缘引起的电压施加在第一电容器和泵电路两端时,第一和第二电容器与基本上由第二电容器确定的电荷串联充电。 比较器的第一输入端连接到第一电容器和泵电路之间的连接点,并且比较器的第二输入端连接到比较电位,以便指示当给定的近似数量的脉冲被计数时 第一电容器两端的电压超过由比较电位确定的阈值电平。
