This paper deals with the attachment of the Frequency Response Slide Rule. The slide rule which has been published in "Automatic Control" Vol.1 (1953) No.3 by K.IZAWA, is used for frequency response computation of real linear factors : (1+Ts), Ks and K/s and exponential factor : e^<-Ls> of such a transfer function as [numerical formula] The attachment is a transparent sheet upon which a logarithmic scale of hyperbolic sine function is graduated with two reference lines. The frequency response of the quadratic factor (1+2ζTs+T^2s^2) of the above transfer function is easily computed by the slide rule and the attachment, when the input frequency ω, 0^.001⦤ω⦤1000,the time constant T, 0^.01⦤T⦤100,and the relative damping ζ, 0^.005⦤ζ⦤2,are given. Three steps are necessary for the computation ; the first step is the setting of the cursor and the slide, the second and third steps are the settings of the attachment.
