Abstract: Tuning of a filter circuit is accomplished by determining a real RC time constant value for the filter circuit, then comparing the real RC vale to a predetermined RC value. If the real RC value does not match the predetermined RC value, the real RC value is varied (e.g. using a number of capacitors in a capacitor arr

Abstract translation: 通过确定滤波电路的实际RC时间常数值，然后将实际RC值与预定的RC值进行比较来实现滤波器电路的调谐。 如果真正的RC值与预定的RC值不匹配，则实际的RC值是变化的（例如，使用电容器中的多个电容器
