Null-Balance Technique for Filter MeasurementWireless Engineer (1952)
The following description of a new measuring technique may be of general interest. There is no difficulty in measuring the cut-off attenuation of a high-pass filter when there are available a tone-source of low harmonic content, subsidiary filters, and a wave-analyser as a measuring instrument. In the absence of such apparatus, however, the technique described here can be used to achieve closely equivalent accuracy.
