Abstract : This patent discloses a method for making tuned resonance passive electronic filters. The method consists of computing the values of the filter components and then using standard unmatched components that approximate the computed values in conjunction with certain components that are made variable for the purpose of tuning out the unmatched characteristics of the unmatched components. A typical filter may include several poles where each pole includes an unmatched component, such as a capacitor, and a variable component such as an inductor. Adjacent poles may be coupled by unmatched or variable inductors or capacitors. Each pole is tuned for resonance by applying the output of a signal generator to a particular pole, while shorting adjacent poles, and tuning the variable component of that pole for resonance. Resonance may be indicated by a null on an a.c. voltmeter connected to measure pole. (Author)
