While the title of this paper is technically correct, it perhaps would have been better to entitle it "Curve Fitting, by Analog Simulation Methods, to Obtain the Transfer Function of a Crustacean Muscle Bundle," since this short paper is almost entirely concerned with the analog techniques used to measure the amplitude and phase response of a transfer function subjected to a sinusoidal input forcing function. If the input sinusoidal frequency is slowly swept across the frequencies of interest, then such measuring circuits (if they are fast enough) will allow the experimenter to generate a continuous Bode plot (i.e., gain and phase versus frequency) of the simulated transfer function.
