An approach to the design of constant-resistance amplitude equalizer networks

It is often desirable to correct or to adjust the amplitude/frequency response of a network to meet certain stated requirements. Although it is usually not difficult to calculate the insertion loss of a correcting network, the inverse is rather more difficult. The paper suggests a method of designing constant-resistance amplitude equalizers to give a desired slope over the working range concerned. A typical example, involving the technique developed, is given in order to illustrate the method of adjusting the response of a velocity-type pick-up over part of the audio-frequency spectrum.
