Fixed attenuators consisting of a network of identical resistors
C.H. Vincent · Journal of Scientific Instruments · 1961
Fixed attenuators constructed of identical resistors have advantages of freedom from distortion by the stray self-inductance of the resistors and freedom from the effects of ambient temperature changes. A suitable form for such attenuating networks is described. It is possible to design a network of this form to give attentuation in any ration N to 1, where N is an integer. The minimum number of resistors needed for any value of N is not excessive, being less than seven resistors per decade of N. A table is given which makes the calculation of an optimum network very easy for any value of N up to 400.
